RIR Comparative Policy Overview 2009-01

RIR Comparative Policy Overview (version 2009-01)

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 While this document was accurate on the date of publication (1 April 2009), it may be outdated by subsequent policy implementations.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.

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

[ TOP ]

1.3.2 Transfer of Custodianship

RIR Policy
AFRINIC

ARIN

LACNIC

Do not allow sale of addresses, but recognise name changes and
transfers of tangible assets associated with addresses. Requires submission
of legal documents. Utilisation is verified. May require new agreement.
APNIC As above, with the exception of “historical resource transfers”.
“Historical” resources can be transferred to APNIC members without the need
for the technical justification procedures.
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 allotion 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 recognises name changes and transfers of tangible assets associated with addresses. Requires submission of legal documents. Utilisation is verified. May require new agreement.

(Aggregatable/Non-Portable)

2.5.1 Assignment Window

RIR Policy Comment
AFRINIC
ARIN
Not applicable. Assignment practices are audited by RIR staff at time of request
for additional resources.
APNIC
LACNIC
RIPE NCC
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.
In RIPE, a new LIR’s Assignment Window (AW) is automatically set to a /21 (2048 addresses) six months after receiving their first allocation.

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).

ARIN

LACNIC

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 In addition to above, from 1 July 2009, APNIC will process applications that specifically request 16 bit AS Numbers and assign such AS Numbers as requested by the applicant if the application can demonstrate that a 32-bit only AS Number is unsuitable. In the absence of demonstrated need for a 16-bit AS Number, a 32-bit only AS Number will be assigned by APNIC.

Not applicable. Assignment practices are audited by RIR staff at time of request
for additional resources.
APNIC
LACNIC
RIPE NCC
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.
In RIPE, a new LIR’s Assignment Window (AW) is automatically set to a /21 (2048 addresses) six months after receiving their first allocation.

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).

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 In addition to above, from 1 July 2009, APNIC will process applications that specifically request 16 bit AS Numbers and assign such AS Numbers as requested by the applicant if the application can demonstrate that a 32-bit only AS Number is unsuitable.
