Making Internet Number Resource Allocations to Regional Internet Registries

IPv4 Address Allocations

When an RIR has less than half a /8 in its inventory it should notify us to begin allocations to all the RIRs from the Recovered IPv4 Pool. This is a one-time event, as allocations are made on a schedule and not in response to specific requests from each RIR; only one RIR needs to make the request for us to begin allocation to all RIRs. Notification that an RIR has less than half of a /8 in its inventory should be sent to ipv4-request@iana.org.

The formula for distributing addresses from the recovered pool can be found at ICANN‘s website.

IPv6 Address Allocations

RIRs requesting additional IPv6 address space because they have less than 50% of a /12 need to provide us with a summary of how much IPv6 address space the RIR has allocated and/or reserved and how much is fragmented. The request and the summary documenting the distribution of the allocated space should be submitted in the spreadsheet template to ipv6-request@iana.org.

An RIR requesting additional IPv6 address space because it does not have enough space for the next nine months must provide us with the amount of address space allocated by the RIR in each of the last six months. The request and the summary should be submitted in the spreadsheet template to ipv6-request@iana.org.

The formula for determining eligibility for additional IPv6 allocations can be found at ICANN‘s website.

AS Number Allocation

An RIR requesting additional AS Numbers because it has assigned/allocated over 80% of its last block of AS Numbers needs to provide a summary of assignments/allocations it has made. If the RIR is requesting more than one block of AS Numbers, it needs to provide a usage summary for the six months prior to the request. Requests for additional AS Numbers should be submitted in the spreadsheet template to asn-request@iana.org.

An RIR requesting additional AS Numbers because the number of free AS Numbers it holds is less than two months needed, must provide a usage summary for the six months prior to the request. Requests for additional AS Numbers should be submitted in the spreadsheet template to asn-request@iana.org.

The global policy for allocation of AS numbers can be found at ICANN‘s website.

Change in Named Registrant

Requests to change the registrant associated with an INR allocation should be sent to iana@iana.org by the current registrant. The current and new registrant will both be contacted to confirm or reject the change request before we will update the registration.
