RIR Comparative Policy Overview (version 2017-03)
(version 2017-02)
The goal of this document is to provide a comparative overview of policies across the Regional Internet Registry (RIR) system. It is not a policy statement by the RIRs, but serves as a reference for the Internet community. While this document was accurate on the date of publication, it may be outdated by subsequent policy implementations. The official policy documents can be found at the respective websites of the RIRs. This is a public document that will be reviewed and revised quarterly through the coordinated efforts of the RIRs.
For more information, refer to the AFRINIC, APNIC, ARIN, LACNIC, and RIPE NCC websites.
1. General
1.1 Goals of the RIR System
RIR | Policy |
---|---|
|
All allocations and assignments of Internet resources must be consistent with the goals of the Internet Registry system: aggregation, conservation and registration. |
1.2 Membership
RIR | Category | Policy |
---|---|---|
AFRINIC | Qualification | Membership is open only to organizations or persons legally present and providing services in the AFRINIC service region. |
Access to delegation and registration services | Registration service is available to members only. AFRINIC manages and distributes Internet Number Resources for its service region only.
|
|
Fee model | Not-for profit. Fee established to enable cost recovery of operations. | |
APNIC | Qualification | Membership is open to all organizations and individuals. |
Access to delegation and registration services | APNIC delegates resources only to organizations, which are legally present, or have networks located in the APNIC region.
Organizations located outside the APNIC service region must use resources delegated by APNIC within the service region. APNIC permits organizations located within the APNIC service region to use APNIC delegated resources out of region.
|
|
Fee model | Not-for-profit. Fee schedule established to enable cost recovery of operations. | |
ARIN | Qualification | Membership is open only to organizations legally present in the ARIN service region.
Organizations that receive direct allocations automatically become members. Membership is also open to organizations with direct assignments, or ARIN issued Autonomous System Numbers. Entities with a signed LRSA / RSA and Internet number resources from ARIN (end users, for example) may become members by filling out the application and paying an annual $500 membership fee or requesting to enroll in ARIN’s Registration Services Plan. |
Access to delegation and registration services | Do not need to be a member to receive registration services. ARIN manages and distributes Internet number resources within its region. To receive resources, ARIN requests organizations to verify that:

|
Fee model | Not-for-profit. Fee schedule established to enable cost recovery of operations. | |
LACNIC | Qualification | Membership is open to LACNIC region only, without conditions. |
Access to delegation and registration services | Numbering resources under the stewardship of LACNIC must be distributed among organizations legally constituted within its service region and mainly serving networks and services operating in this region.
LACNIC requires organizations to be legally present and have network infrastructure in the LACNIC service region to apply for and receive resources.
|
|
Fee model | Not-for-profit. Fee schedule established to enable cost recovery of operations. | |
RIPE NCC | Qualification | Membership is open without conditions. |
Access to delegation and registration services | Access to registration services is available to members only.
Legacy resource holders who have a non-member service contract with the RIPE NCC can also access some registration services. The RIPE NCC delegates or registers resources to organizations and individuals that have a need in its service region. The network that will be using the resources must have an active element located in the RIPE NCC service region. |
|
Fee model | Not-for-profit. Fee schedule established to enable cost recovery of operations. |
1.3 Allocation Terms and Conditions
1.3.1 Type of Custodianship
RIR | Policy |
---|---|
AFRINIC | Valid as long as original criteria remain satisfied. |
APNIC | Allocates and assigns on a “license” basis, to be of specific limited duration (normally 1 year). Licenses are renewable if:
|
ARIN | Valid as long as organization remains in compliance with policy and registration fees are kept up to date. |
LACNIC | Valid as long as original criteria remain satisfied and registration fees are kept up to date. |
RIPE NCC | Valid as long as original criteria remain satisfied. |
1.3.2 Transfer of Custodianship
RIR | Policy |
---|---|
AFRINIC | Allows transfer of IPv4 addresses within the AFRINIC service region. The IPv4 resources to be transferred must be from an existing AFRINIC member’s account or from a Legacy Resource Holder in the AFRINIC service region.
Conditions on the source of the transfer:
Conditions on the recipient of the transfer:
|
APNIC | APNIC recognizes resource transfers under the following conditions:
|
ARIN | IPv4 number resources and ASNs within the ARIN region may be released to ARIN by the authorized resource holder, in whole or in part, for transfer to another specified organizational recipient.
Organizations without direct assignments or allocations from ARIN qualify for transfer of an initial IPv4 block of ARIN’s minimum transfer size. Organizations may qualify for the transfer of a larger initial block, or an additional block, by providing documentation to ARIN which details the use of at least 50% of the requested IPv4 block size within 24 months. Organizations with direct assignments or allocations from ARIN must have efficiently utilized at least 50% of their cumulative IPv4 address blocks in order to receive additional space. Organizations may also qualify for additional IPv4 address blocks (up to a /16 once every 6 months) by demonstrating 80% utilization of their currently allocated space. An officer of the organization shall attest to the documentation provided to ARIN. The recipient must demonstrate the need for up to a 24-month supply of IP address resources under current ARIN policies and sign an RSA. Reserved pool resources are ineligible. Inter-regional transfers of IPv4 number resources may take place only via RIRs who agree to the transfer and share reciprocal, compatible, needs-based policies. ARIN also recognizes name changes and transfers due to mergers, acquisitions and reorganizations. Requires documentation that the assets using the resources or the other organization as a whole has been acquired. These transfers are not subject to additional needs assessments. |
LACNIC | Internet resources assigned by LACNIC may be the object of transfers within the LACNIC service region. Such transfers will be acknowledged provided that they fall within the following situations:
Note: Inter-RIR transfers (i.e., transfers outside the LACNIC service region) are not allowed. |
RIPE NCC | Member LIRs can transfer complete or partial blocks of IPv4 and IPv6 address space that was previously allocated to them by either the RIPE NCC or the IANA within the RIPE NCC service region. The receiving LIR must confirm it will make assignment(s) from the allocation.
Resource holders of IPv4 Provider Independent (PI) and IPv6 PI space that was previously assigned to them by the RIPE NCC can also transfer complete or partial blocks within the RIPE NCC service region. When transferring PI space, the recipient of the transfer must confirm a specific intended purpose for the resources in order to receive the reassignment. Scarce resources, which are understood as those resources that are allocated or assigned by the RIPE NCC on a restricted basis (such as IPv4 or 16-bit ASNs), cannot be transferred for 24 months from the date the resource was received by the resource holder. This restriction also applies if the resource was received due to a change in the organisation’s business (such as a merger or acquisition). This restriction does not prevent the resources from being transferred due to further mergers or acquisitions within the 24-month period. Inter-RIR transfers of any type of Internet number resource are possible if both RIRs have compatible transfer policies. For transfers to the RIPE NCC service region from RIRs that have needs-based policies, recipients must provide the RIPE NCC with a plan for the use of at least 50% of the transferred resources within five years. RIPE NCC also recognizes name changes and transfers of tangible assets associated with addresses. This requires the submission of legal documentation. Utilization is verified. This may also require new agreement. |
1.3.3 Recovering Unused Resources
RIR | Policy | Comment |
---|---|---|
|
Valid as long as original criteria remain satisfied. | Do not actively recover unused resources, but if an organization closes, unused resources are returned to the public pool. |

(Aggregatable/Non-Portable)
2.5.1 Assignment Window
RIR | Policy | Comment |
---|---|---|
|
Not applicable. | Assignment practices are audited by RIR staff at time of request for additional resources. |
|
LIRs/ISPs need approval from the RIR when making assignments larger than their Assignment Window. This is the number of addresses an LIR/ISP can assign without prior approval. The RIR sets the assignment window according to the LIR’s/ISP’s level of experience with the policies. |
APNIC does not have assignment windows on infrastructure. |
RIPE NCC | Not applicable. | LIRs can set their own rules on assignment period and utilization. They are not required to complete a forecast-based documentation of need when requesting IPv4 allocations from the RIPE NCC. |
2.5.2 Dynamic Addressing

2.6. Use of Final Unallocated IPv4 Address Space
RIR | Category | Policy |
---|---|---|
AFRINIC | Size | See below. |
Eligibility | EXHAUSTION PHASE 1:
EXHAUSTION PHASE 2:
|
|
APNIC | Size | /24 up to a maximum of /22. |
Eligibility | Since APNIC reached an equivalent of a /8 remaining in the APNIC pool on 14 April 2011:
After 4 August 2017, all returned address space from the 103/8 (Final /8) block will be returned to the 103/8 pool (not the Recovered IPv4 pool), for redistribution under Final /8 policies. |
|
ARIN | Size | /28 minimum, /24 maximum. |
Eligibility | Allocations and assignments are from a reserved /10 and must be justified by immediate IPv6 requirements. | |
LACNIC | Size | /24 up to a maximum of /22. |
Eligibility | LACNIC will create a reserve of the last available space which will consist of IPv4 block post exhaustion allocated by IANA plus recovered and returned IPv4 blocks. Allocations and assignments from this pool will ONLY be done to NEW MEMBERS. IPv4 address requests classified as critical infrastructure according to the LACNIC policies in force may receive addresses, even if they have already been assigned IPv4 resources by LACNIC. LACNIC may only make IPv4 allocations or assignments greater than or equal to a /24 and smaller than or equal to /22, IPv4 address blocks larger than a /22 pending approval may only receive a /22, when this reserve is reached. No further allocations or assignments will be possible after receiving resources under this policy, unless more resources are assigned from IANA. Blocks or sub-blocks received under this policy may not be transferred for a period of one year. If the applicant does not already have an IPv6 address block assigned by LACNIC, it must also request an IPv6 address block in accordance with the corresponding applicable policy. The reserve created under section 11.2 is independent from the reserve created under this policy. LACNIC will reserve an equivalent to another /10 block of IPv4 addresses for the purpose of achieving gradual exhaustion of IPv4 resources within the LACNIC region. LACNIC may only make IPv4 allocations or assignments greater than or equal to a /24 and smaller than or equal to /22 from this reserve pool. Organizations that receive IPv4 resources under the terms set forth in the following policy may receive additional IPv4 resources from LACNIC six months later. IPv4 address requests classified as critical infrastructure according to the LACNIC policies in force may receive addresses, even if they have already been assigned IPv4 resources by LACNIC. Blocks received under this policy may not be transferred as specified in paragraph 2.3.2.18 of the policy manual for a period of one year. Resources allocated by IANA to LACNIC after achieving the final /11 block for gradual exhaustion (section 11.2 of the Policy Manual), will only be allocated / assigned under the guidelines set forth on item 11.1 of the Policy Manual. |
|
RIPE NCC | Size | /22 |
Eligibility | 1. Allocations for LIRs from the last /8:
On application for IPv4 resources LIRs will receive IPv4 addresses according to the following:
2. Assignments to Internet Exchange Point: A /16 from the final /8 will be held in reserve for exclusive use by Internet Exchange Points. On application for IPv4 resources, an Internet Exchange Point (IXP) will receive one number resource (/24 to /22) according to the following:
3. Unforeseen circumstances: A /16 will be held in reserve for some future uses, as yet unforeseen. The Internet is a disruptive technology and we cannot predict what might happen. Therefore it is prudent to keep a /16 in reserve, just in case some future requirement makes a demand of it. In the event that this /16 remains unused at the time the remaining /8 covered by this policy has been distributed, it returns to the pool to be distributed as per clause 1. 4. Post-depletion Address Recycling: This section only applies to address space that is returned to the RIPE NCC and that will not be returned to the IANA but re-issued by the RIPE NCC itself.
|
2.7 Use of IANA Recovered Address Space
RIR | Policy |
---|---|
AFRINIC | – |
APNIC | From 27 May 2014, following the allocation to APNIC of additional IPv4 addresses from the IANA IPv4 Recovered Address Space pool, each account holder (current and future) will be eligible to request and receive additional delegations up to a maximum of /22 from the new IPv4 pool (non-/103 pool). The application criteria for receiving a subsequent IPv4 delegation from this pool is the same as that for delegations under the ‘final /8′ (/103) pool. |
ARIN | – |
LACNIC | Resources allocated by IANA to LACNIC once item 11.2 of the Policy Manual (Allocations/Assignments for Gradual IPv4 Resource Exhaustion) becomes effective will only be allocated/assigned under the guidelines set forth on item 11.1 of the Policy Manual (Special IPv4 Allocations/Assignments Reserved for New Members). |

Eligibility |
|
||
Period | Up to one year. | ||
APNIC | Size | /32. | Allocations consistent with the globally co-ordinated ‘IPv6 Address Allocation and Assignment Policy’ document. Organizations may qualify for an initial allocation greater than /32 by submitting documentation that reasonably justifies the request.
Considers IPv4 deployment as one of the means of justifying a larger initial allocation. |
Eligibility | APNIC members with IPv4 resources managed by APNIC but with no IPv6 resources automatically qualify for an appropriately sized IPv6 block. Organizations with no IPv4, or that wish to request more than a /32 should meet the following requirements:
|

Period | For up to one year. | ||
ARIN | Size | /36, /32, /28, /24, /20, /16 | The maximum allowable allocation shall be the smallest nibble-boundary aligned block that can provide an equally sized nibble-boundary aligned block to each of the requesters serving sites large enough to satisfy the needs of the requesters largest single serving site using no more than 75% of the available addresses. |
Eligibility | Organizations must meet any of the following criteria:
|
||
Period | For up to five years. | ||
LACNIC | Size | /32. | As a special case, LACNIC has a policy for the “Second Allocation” where an Organization that holds only one IPv6 allocation can return it (within the first 6 months of getting it) in order to receive another shorter prefix allocation from LACNIC.
For allocations larger than a /32, the Organization must address the considerations specified in section 4.5.1.3 of the Policy Manual. |
Eligibility | Hold an IPv4 allocation from LACNIC and announce the allocated block with the minimum possible level of disaggregation to the one that is publishing the IP blocks, or:
|
||
Period | For up to one year. | ||
RIPE NCC | Size | /32 minimum | Organizations that meet the initial allocation criteria are eligible to receive an initial allocation of /32. For allocations up to /29 no additional documentation is necessary.
Allocation size larger than /29 will be based on the number of users, the extent of the organization’s infrastructure, the hierarchical and geographical structuring of the organization, the segmentation of infrastructure for security and the planned longevity of the allocation. |
Eligibility |
|

AFRINIC | Size | Minimum size of next allocation will equal the first allocation size. More can be allocated but justification must be supplied. | Contiguous allocation provided if possible.
RFC 3194 defines the HD-Ratio. |
Eligibility | ISP/LIR must satisfy the evaluation threshold of past address utilization in terms of the number of sites in units of /48 assignments. The HD-Ratio of 0.94 is used to determine the utilization thresholds that justify the allocation of additional addresses. | ||
Period | Up to one year. | ||
APNIC | Size | Minimum size of next allocation will equal the first allocation size. More can be allocated but justification must be supplied. | Contiguous allocation provided if possible.
RFC 3194 defines the HD-Ratio. Guidelines on what will be considered a valid technical requirement is available at: |
Eligibility | ISP/LIR must satisfy the evaluation threshold of past address utilization in terms of the number of sites in units of /56 assignments. The HD-Ratio of 0.94 is used to determine the utilization thresholds that justify the allocation of additional addresses.
Alternative criteria may be considered where an organization can demonstrate a valid reason for requiring a subsequent allocation. |

Period | Up to two years. | ||
RIPE NCC | Size | Minimum size of next allocation will equal the first allocation size. More can be allocated but justification must be supplied. | Contiguous allocation provided if possible.
RFC 3194 defines the HD-Ratio. |
Eligibility | Subsequent allocation will be provided when an organisation (i.e. ISP/LIR):
a) Satisfies the evaluation threshold of past address utilisation in terms of the number of sites in units of /56. To this end, the HD-Ratio [RFC 3194] is used to determine the utilisation thresholds. or b) Can justify new needs (which can’t be satisfied within the previous allocation), according to the initial allocation size criteria. |
||
Period | Up to two years. | ||
ARIN | Size | Where possible ARIN will make subsequent allocations by expanding the existing allocation.
If ARIN can not expand one or more existing allocations, ARIN shall make a new allocation based on the initial allocation criteria above. The LIR is encouraged, but not required to renumber into the new allocation over time and return any allocations no longer in use. If an LIR has already reached a /12 or more, ARIN will allocate a single additional /12 rather than continue expanding nibble boundaries. |
Subsequent allocations will also be considered for deployments that cannot be accommodated by, nor were accounted for, under the initial allocation. Justification for the subsequent subnet size will be based on the plan and technology provided with a /24 being the maximum allowed for a transition technology. Justification for transitional allocations will be reviewed every 3 years and reclaimed if they are no longer in use for transitional purposes. All such allocations for transitional technology will be made from a block designated for this purpose. |
Eligibility |
|
||
Period | Up to five years. | ||
LACNIC | Size | Minimum size of next allocation will equal the first allocation size. More can be allocated but justification must be supplied. | Contiguous allocation provided if possible.
RFC 3194 defines the HD-Ratio. |
Eligibility | ISP/LIR must satisfy the evaluation threshold of past address utilization in terms of the number of sites in units of /48 assignments. The HD-Ratio of 0.94 is used to determine the utilization thresholds that justify the allocation of additional addresses. | ||
Period | Up to two years. |

APNIC | Blocks of ASNs are allocated to NIRs for further distribution to their members. |
|
Not applicable. |
4.2 Assignments
RIR | Category | Policy |
---|---|---|
|
Eligibility | Policies for ASN assignments are aligned with the guidelines contained in RFC1930. Verify that a network will have a unique routing policy or that it will be a multihomed site before assigning an ASN. |
APNIC | Eligibility | ASNs may be obtained directly from APNIC as a member or non-member account holder. The ASN obtained directly is portable. ASNs may also be obtained indirectly, through a LIR who ‘sponsors’ the request. In this event, the ASN is non-portable.
Criteria need to be met in both cases, that is: An organization is eligible if it:
An organization will also be eligible if it can demonstrate that it will meet the above criteria upon receiving an ASN (or within a reasonably short time thereafter). Requests for ASNs under these criteria will be evaluated using the guidelines described in RFC1930. |
LACNIC | Eligibility | LACNIC shall allocate Autonomous System Numbers to those organizations that meet the following requirements:
|
4.2.1 32-bit ASNs
RIR | Policy |
---|---|
|
From 1 January 2007 the RIR will process applications that specifically request 32-bit only AS Numbers (AS numbers that cannot be represented with 16 bits) and assign such AS Numbers as requested by the applicant. In the absence of any specific request for a 32-bit only AS Number, the RIR will assign a 16-bit AS Number.
From 1 January 2009 RIR will process applications that specifically request 16-bit AS Numbers and assign such AS Numbers as requested by the applicant. In the absence of any specific request for a 16-bit AS Number, the RIR will assign a 32-bit only AS Number. From 1 January 2010 the RIR will cease to make any distinction between 16-bit AS Numbers and 32-bit only AS Numbers, and will operate AS Number assignments from an undifferentiated 32-bit AS Number allocation pool. |
APNIC | From 1 January 2010, APNIC ceased to make any distinction between two-byte only AS numbers and four-byte only AS numbers, and operates AS number assignments from an undifferentiated four-byte AS number pool. |
LACNIC | From 1 January 2007 the RIR will process applications that specifically request 32-bit only AS Numbers (AS numbers that cannot be represented with 16 bits) and assign such AS Numbers as requested by the applicant. In the absence of any specific request for a 32-bit only AS Number, the RIR will assign a 16-bit AS Number.
From 1 January 2009 RIR will process applications that specifically request 16-bit AS Numbers and assign such AS Numbers as requested by the applicant. In the absence of any specific request for a 16-bit AS Number, the RIR will assign a 32-bit only AS Number. From 1 January 2010, LACNIC shall allocate 32-bit AS numbers by default. 16-bit AS numbers shall be allocated, if available, in response to applications specifically requesting said resource and that duly justify the technical reasons why a 32-bit AS number would not be appropriate for its needs. |

6. Reverse DNS
RIR | Policy | Comment |
---|---|---|
AFRINIC |
|
Members may only obtain rDNS if address space issued (assigned or sub-allocated) is recorded in the AFRINIC whois Database. |
APNIC | Provides reverse DNS based on domain objects in the APNIC database. If the delegation is /16 or larger then the authority for the reverse zone, it is delegated to the custodian of the address space. | Policy for “lame delegations” checking established and enforced. |
ARIN | Not applicable. | ARIN’s delegation management tools enable you to individually manage each reverse delegation within both IPv4 and IPv6 networks. Delegations can be managed in IPv4 on byte boundaries (/8, /16 or /24’s), and IPv6 networks can be managed on nibble boundaries (every 4 bits of the IPv6 address). |
LACNIC | Provides reverse DNS for all parent blocks. Does not provide reverse DNS for reassignments on child blocks if the parent is /16 or greater. | Policy for “lame delegations” checking established and enforced |
RIPE NCC | Provides reverse DNS delegation on request. Deploys DNSSEC on all the reverse zones. | RIPE NCC verifies RFC1912 compliance. |
7. National Internet Registries (NIRs)
RIR | Policy |
---|---|

Allocations and assignments of Internet resources for Internet experiments are available. Such allocations or assignments are made for one year after which they must be returned. They are intended to support experimental Internet activities. Results of experiments must be made freely available to the public. |
ARIN | ARIN will allocate Numbering Resources to entities requiring temporary Numbering Resources for a fixed period of time under the terms of recognised experimental activity. |
RIPE NCC | RIPE NCC uses a reserved pool of Internet resources for temporary assignment. For conferences and other events of short, fixed duration, the maximum assignment time period will be one month longer than the scheduled length of the conference/event but no longer than two months in any case.
The assignment time limits for longer-term projects and research purposes are up to six calendar months. In the case where an End User requires number resources for research purposes, and where the research project details are made public upon registration End User commits to making public the results of their research project free of charge and free from disclosure constraints, then the requested number resources may be issued for a period of up to one calendar year. |
LACNIC | LACNIC shall make experimental allocations with the aim of encouraging research and development within the region of Latin America and the Caribbean. The experimental allocation shall be for a period of one year, renewable for a period of the same duration, with no specified maximum.
