FAQ: IPv4 and Reaching the last /8
- The RIPE NCC is now allocating IPv4 address space from its last /8. What happens now?
The pool of available IPv4 addresses was exhausted on 1 February, 2011, triggering the "Global Policy for the Allocation of the Remaining IPv4 Address Space".
On 3 February, 2011, the five RIRs each received one of the IANA's five reserved /8 blocks. One /8 is equal to 16.8 million IPv4 addresses. Each RIR has community specific policies dealing with how this /8 is distributed within their respective communities.
The RIPE NCC is now allocating IPv4 address space from the last /8 according to "IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region". Each Local Internet Registry (LIR) can receive only one /22 (1,024 IPv4 addresses) upon application for IPv4 resources. No new IPv4 Provider Independent (PI) space will be assigned.
- Who decided that each RIR would receive one of the reserved /8s?
The "Global Policy for the Allocation of the Remaining IPv4 Address Space" was proposed, discussed, modified and accepted by all five of the RIR communities in an open, inclusive and fully documented process. The policy was ratified by the ICANN Board on 6 March 2009.
- How much available IPv4 space does the RIPE NCC have available for allocation?
The amount of space in the RIPE NCC's IPv4 available pool can be seen here.
- Who decided how the RIPE NCC will distribute the final /8 it received from IANA?
The RIPE community decided how the RIPE NCC would distribute the last /8. All policies are developed using the open, transparent and consensus based RIPE Policy Development Process (PDP). The RIPE NCC does not propose, accept or reject any policies.
- How did the pool of IPv4 addresses run out?
No one could have predicted the growth of the Internet and, when the commercial Internet was in its infancy, the pool of around 4 billion IPv4 addresses seemed huge. IPv4 addresses were in use before the RIRs existed. The introduction of the RIR system helped to regulate the consumption of IPv4 addresses by allocating and assigning Internet number resources based on need.
- Can I transfer or exchange IPv4 addresses?
The IPv4 Transfer Listing Service is a platform that enables RIPE NCC members to list for exchange the IPv4 address space they hold and no longer need. The listing service is only available to members and its use is included in the annual RIPE NCC membership fee.
- Where can find training on how to deploy IPv6?
There are several individuals and organisations offering IPv6 training and consultancy. Some of them are listed here.
- Where can I get more information about IPv6?
The IPv6 Act Now website offers information about IPv6 and its deployment for all stakeholders.
- Can I get a /22 of IPv4 space from the last /8 if I am not an LIR?
No. You have to be an LIR to receive a /22 allocation from the last /8.
See "IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region" for more information.
- Can I get an IPv4 PI assignment from the last /8?
No. Only IPv4 allocations can be distributed from the last /8. Only LIRs can receive an allocation.
See section 5.1 of "IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region" for more information.
- How can I get a /22 allocation from the last /8?
The RIPE NCC is allocating IPv4 address space from the last /8 according to "IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region". This means that LIRs may receive one final /22 allocation from the last /8 of IPv4 address space.
- What does the RIPE NCC do with IPv4 address space that is returned?
All IPv4 address space that is returned to the RIPE NCC goes back into the last /8 pool of IPv4 address space. It will then be re-used to allocate /22s to LIRs according to "IPv4 Address Allocation and Assignment Policies for the RIPE NCC Service Region".
