RIR Comparative Policy Overview (version 2012-02)

(version 2012-02)

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 While this document was accurate on the date of publication, it may be outdated by subsequent policy implementations.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
AFRINIC APNIC ARIN LACNIC RIPE NCC	All allocations and assignments of Internet resources must be consistent with the goals of the Internet Registry system: aggregation, conservation and registration.

RIR	Category	Policy
AFRINIC	Qualification	Membership is open to organizations legally present in the AFRINIC region of service.
	Access to registration services	Registration service is accessible by members only. Registered resources are publicly available.
	Fee model	Not-for profit. Fee established to enable cost recovery of operations.
APNIC	Qualification	Only organizations that are located in the APNIC region or have networks located in the APNIC region may apply for resources.
	Access to registration services	Members have full access to all services. Non-member account holders may access resource assignment and allocation services.
	Fee model	Not-for-profit. Fee schedule established to enable cost recovery of operations.
ARIN	Qualification	Organizations that receive direct allocations automatically become members. Membership also open to organizations with direct assignments or ARIN issued Autonomous System Numbers.
	Access to registration services	Do not need to be a member to receive registration services.
	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 registration services	Organizations approved for IP addresses automatically become members. It is not necessary to become a member to obtain some services like ASN assignments. Only organizations based in LACNIC region may apply for 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 registration services	Members only. Direct Assignment Users who have a contract with the RIPE NCC can also access Registration Services.
	Fee model	Not-for-profit. Fee schedule established to enable cost recovery of operations.

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: a) the original basis of the allocation or assignment remains valid and b) requirements have been met at time of renewal.
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.

RIR	Policy
AFRINIC	Does not allow sale of addresses, but recognises name changes and transfers of tangible assets associated with addresses. Requires submission of legal documents. Utilization is verified. May require new agreement.
APNIC	APNIC recognizes resource transfers under the following conditions:1) Historical resources may be transferred to an APNIC Member account. Transfers are purely optional and do not need to meet any technical justifications.2) APNIC recognizes transfers of IPv4 address blocks of /24 or greater between APNIC account holders. Recipients are required to justify their need for the resources.3) Transfers of IPv4 address blocks greater than /24 are recognized between APNIC account holders and account holders in other regions, only where that region has a suitable Inter-RIR transfer policy. The APNIC account holder must meet the requirements of APNIC policy and the entity in the other region must meet the policy requirements and criteria in its own region. If the recipient is in the APNIC region, they are required to justify their need for the resources.4) APNIC recognizes the transfer of any numeric resource resulting from mergers, acquisitions, and takeovers, where the effect of the new ownership is that an LIR changes its name. Supporting legal documentation is, as is full disclosure of all address space held by all entities involved.
ARIN	IPv4 number resources 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. Resources may only be received under RSA by organizations that are within the ARIN region and can demonstrate the need for such resources in the amount which they can justify under current ARIN policies. ARIN also recognizes name changes and transfers due to mergers and acquisitions. Requires documentation and demonstration of need.
LACNIC	Does not allow sale of addresses, but recognizes name changes and transfers of tangible assets associated with addresses. Requires submission of legal documents. Utilization is verified. May require new agreement. Once LACNIC or any of its NIRs becomes unable, for the first time, to cover an IPv4 block allocation or assignment because of lack of resources, LIRs and/or End Users within the LACNIC region will be allowed to transfer IPv4 blocks.
RIPE NCC	Member LIRs can transfer complete or partial blocks of IPv4 address space that were previously allocated to them by either the RIPE NCC or the IANA to another LIR. Such address space must not contain any block that is assigned to an End User. An LIR may only receive a transferred allocation after their need is evaluated and approved by the RIPE NCC according to the existing allocation policies. LIRs that receive a transfer from another LIR cannot re-allocate complete or partial blocks of the same address space to another LIR within 24 months of receiving the re-allocation. RIPE NCC also recognizes name changes and transfers of tangible assets associated with addresses. Requires submission of legal documents. Utilization is verified. May require new agreement.

RIR	Policy	Comment
AFRINIC	LIRs may sub-allocate addresses to other organizations, which further assign addresses to End Users. LIRs also assign addresses. Sub-allocations are subject to the “Sub-Allocation Window” procedure.
APNIC	LIRs may sub-allocate addresses to other organizations, which further assign addresses to end-users. LIRs also assign addresses. Sub-allocations are subject to the “Assignment Window” procedure.	See section 2.5.1 “Assignment Window” below.
ARIN	ISPs may sub-allocate addresses to other organizations, which further assign addresses to End Users.
LACNIC	RIR allocates and assigns IP blocks to organizations that can be ISPs, End Users or National Internet Registries, (NIRs – see section 7). NIRs allocate and assign IP blocks to organizations in their countries. ISPs may sub-allocate IP blocks to other ISPs or assign them to End Users.
RIPE NCC	An LIR may sub-allocate up to a /20 (4096 addresses) to a downstream network operator every twelve months, who can then assign addresses to End Users. The minimum size of a sub-allocation is a /24.

RIR	Category	Policy
AFRINIC	Size	No special policy.
AFRINIC	Eligibility	No special policy.
APNIC	Size	/24 up to a maximum of /22.
APNIC	Eligibility	Since APNIC reached an equivalent of a /8 remaining in the APNIC pool on 14 April 2011: 1. Each account holder (current and future) will be eligible to request and receive delegations up to a maximum of /22 from the remaining space, providing the account holder meets the criteria for receiving an initial or subsequent IPv4 delegation. 2. A /16 will be held in reserve for future uses, as yet unforeseen. If the reserved /16 remains unused by the time the rest of the remaining /8 worth of space has been allocated, the /16 will be returned to the APNIC pool for distribution under the policy described in the point above
ARIN	Size	/28 minimum, /24 maximum.
ARIN	Eligibility	Policy takes effect upon receipt of ARIN’s last /8 IPv4 allocation from IANA. Allocations and assignments are from a reserved /10 and must be justified by immediate IPv6 requirements.
LACNIC	Size	/22 for ISPs, /24 for Critical Infrastructure
LACNIC	Eligibility	When an equivalent of a /12 is remaining in the LACNIC pool, allocations and assignments will only be done to new members. Allocations to new ISPs will be of size /22 and assignments to critical infrastructure will be of size /24. No further allocations or assignments will be possible after receiving resources under this policy. 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.LACNIC will reserve an equivalent to another /12 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. 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.
RIPE NCC	Size	/22
RIPE NCC	Eligibility	1. Allocations for LIRs from the last /8 On application for IPv4 resources LIRs will receive IPv4 addresses according to the following: a) LIRs may only receive one allocation from this /8. The size of the allocation made under this policy will be exactly one /22. b) LIRs receive only one /22, even if their needs justify a larger allocation. c) LIRs may apply for and receive this allocation once they meet the criteria to receive IPv4 address space according to the allocation policy in effect in the RIPE NCC service region at the time of application. d) Allocations will only be made to LIRs if they have already received an IPv6 allocation from an upstream LIR or the RIPE NCC.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:- This space will be used to run an Internet Exchange Point peering LAN; other uses are forbidden. – Organisations receiving space under this policy must be Internet Exchange Points and must meet the definition as described in section two of the RIPE document “IPv6 Address Space for Internet Exchange Points”. – IXPs holding other PI IPv4 space for their peering LAN (i.e. they are seeking a larger assignment), must return their old peering LAN resources back to this pool within 180 days of assignment. – New Internet Exchange points will be assigned a /24. Internet exchange points may return this /24 (or existing PI used as an IXP peering LAN) should they run out of space and receive a larger (/23, or /22 if utilisation requires) assignment. – IP space returned by Internet Exchange Points will be added to the reserved pool maintained for Internet Exchange Point use. – Assignments will only be made to IXPs who have already applied for, or received an IPv6 assignment for their peering LAN3. Unforeseen circumstance 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. a) Any address space that is returned to the RIPE NCC will be covered by the same rules as the address space intended in clause 1. b) Minimum allocation sizes for the relevant /8 blocks will be updated if necessary 5. Insufficient address space In case an allocation of a single /22 as per clause 1 can no longer be made, multiple allocations up to an equivalent of a /22 in address space will be made to fulfill a request.

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, 2. a) Be a LIR or an ISP; b) Document a detailed plan for the services and IPv6 connectivity to be offered to other organizations; c) Announce the allocated block in the Internet inter-domain routing system, with the minimum possible level of disaggregation to the one that is publishing the IP blocks, within a period no longer than 12 months; d) Offer IPv6 services to clients or entities owned/related (including departments and/or sites) physically located within the region covered by LACNIC within a period not longer than 24 months than 24 months.
	Period	For up to one year.
RIPE NCC	Size	/32 minimum, up to /29	Organisations 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. Considers IPv6 deployment as one of the means of justifying a larger than /29 initial allocation.

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.

Members that do not hold an IPv4 multihoming assignment from APNIC, that have existing IPv6 resources, or that wish to request more than /48 should meet the following requirement: a) An organization is currently multihomed or plans to be multihomed within three months.	These assignments come from a distinctly identified prefix.
ARIN	Size	/48 minimum.	The initial assignment size is determined by the number of sites. Nibble boundary assignments are available.
ARIN	Eligibility	Meet one of the following requirements: 1. have a previously justified IPv4 end-user assignment from ARIN or one of its predecessor registries 2. currently be IPv6 Multihomed or have a plan to immediately become IPv6 Multihomed using an assigned valid global AS number 3. have a network that will makes active use of a minimum of 2000 IPv6 addresses within 12 months 4. have a network that will make active use of a minimum of 200 /64 subnets within 12 months 5. provide a reasonable technical justification indicating why IPv6 addresses from an ISP or other LIR are unsuitable. or,Be a Community Network that will immediately have at least 100 simultaneous users and a demonstrated plan to have at least 200 simultaneous users within one year.
LACNIC	Size	/48 minimum, /32 maximum
LACNIC	Eligibility	Automatic if requestor has IPv4 assignments. Else: 1) Not been an LIR, 2) In case of announcing the assignment on the Internet inter-domain routing system, the receiving organization shall announce the block maintaining de-aggregation to a minimum in accordance with the announcing organization’s needs, 3) submit information showing address use plan for 3, 6 and 12 months, 4) submit network topology, routing and addressing plan.
RIPE NCC	Size	/48 minimum.	Assignments will be made from a separate “designated block”‘ to facilitate filtering practices
RIPE NCC	Eligibility	Meet the requirements of the policies described in the document entitled “Contractual Requirements for Provider Independent Resources Holders in the RIPE NCC Service Region“

RIR	Policy
APNIC	Blocks of ASNs are allocated to NIRs for further distribution to their members.
AFRINIC ARIN LACNIC RIPE NCC	Not applicable.

RIR	Category	Policy
AFRINIC ARIN LACNIC RIPE NCC	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 organisation is eligible if it a) is multihomed; and b) has a single, defined routing policy that is different from its providers’ routing policies. An organisation 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).

RIR	Policy
AFRINIC ARIN RIPE NCC	From 1 January 2007 the RIR will process applications that specifically request 32-bit only AS Numbers (AS numbers that can not 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 can not 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.

RIR	Category	Policy	Comment
AFRINIC	Modification	LIRs are required to register all assignments and sub-allocations.
AFRINIC	Entry	Can update all assignment and sub-allocation registrations (protection mechanism available). Org object cannot be created by a LIR.
APNIC	Modification	LIRs required to register all assignments and sub-allocations. Registrations will be stored privately by APNIC unless the custodian wishes them to be made publicly available in the APNIC Whois Database.	Not required to register infrastructure assignments.
APNIC	Entry	Can update all assignment and sub-allocation registrations (protection mechanism available). Incident Response Team reference mandatory for all IP address and AS number objects in the APNIC Whois Database to assist in reporting network abuse.	Not required to register infrastructure assignments.
ARIN	Modification	Downstream reassignments and reallocations are reported, showing hierarchy and End User assignments.Reassignment information for residential customers need not contain the customer’s name nor street address.	Not required to register infrastructure assignments.
ARIN	Entry	Can modify all parent data except “org name” and address range. Can modify all child data.	Not required to register infrastructure assignments.
LACNIC	Modification	Downstream reassignments and reallocations are reported, showing hierarchy and End User assignments.	Not required to register infrastructure assignments.
LACNIC	Entry	Can modify all parent data except “org name” and address range. Can modify all child data. Users have to authenticate themselves in LACNIC web system.	Not required to register infrastructure assignments.

RIPE NCC	Entry	Can update all assignment and sub-allocation registrations (protection mechanism available).

RIR	Policy	Comment
AFRINIC	Only make delegations on 8-bit boundaries (/16 or /24). Multiple delegations may be requested to cover CIDR prefixes for blocks bigger than a /24.
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	Provides reverse DNS for all allocations and assignments in the database with the following exception: For all /16 or larger blocks ARIN delegates reverse DNS authority to the registrant.	Policy for “lame delegations” checking established and enforced.
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.
