RIPE NCC has Approximately Four Million IPv4 Addresses Before Reaching Last /8

  • admin 

RIPE Announcement

The RIPE NCC has now entered phase one of its approach to reaching the last /8. This means that:

– As of Tuesday, 4 September, we have approximately one month (or a /10) worth of IPv4 address space (4,134,976 addresses) to distribute before we reach the last /8.

– Our IPRAs are now working in pairs to ensure that all requests are dealt with efficiently and to further ensure fairness, consistency and transparency. This means that our response times may be longer than you have previously experienced. You can find the response times for requests for IPv4 address space at:

– Our «call back procedure» has changed. We will now call requestors about their ticket only when their ticket is at the front of the request queue. This will ensure that no ticket is handled outside of the order it was received in.

– Depending on the availability in the RIPE NCC’s free pool of IPv4 address space, you may receive multiple smaller prefixes that add up to the size of your request.

– The quarantine period in place for returned IPv4 address space before it can be re-used will be gradually decreased. In the last days before we reach the last /8, the quarantine period may be reduced to one week or less. This will ensure that there is no IPv4 address space left in the quarantine pool when we start to allocate from the last /8. More information about quarantine periods can be found at:

– The Available IPv4 Pool Graph will be updated daily as of Wednesday, 5 September. You can find this graph online at:

RIPE NCC Returns Legacy Address Space to IANA

  • admin 

On 6 May 2012, the ICANN Board ratified GPP-IPv4-2011, «Global Policy for Post Exhaustion IPv4 Allocation Mechanisms» by IANA.

This global policy enables IANA to redistribute any recovered IPv4 address space equally amongst the RIRs.

Following the ratification of this global policy, on 22 May 2012 the RIPE NCC returned to IANA the 1,368,576 legacy IPv4 addresses that have been returned to the RIPE NCC and plans to return any other legacy

IPv4 address space that is returned to the organisation in the future.
