The RIPE NCC's statistics now list it as 'available'; reissue not confirmed

The RIPE NCC's statistics show it reserved on 2011-11-27 and available on 2011-11-28. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2011-08-29, 91 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold

Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it assigned (dated 2011-06-21) on 2011-08-28 and reserved on 2011-08-29. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for IPv4 space applies to removals from 2014-03-26 on, and this one came earlier, so the tracker gives no estimate. This does not confirm availability.

Likely issued from RIPE NCC-controlled inventory

No transfer record matches. The RIPE NCC's statistics show it available on 2011-06-20 and assigned (dated 2011-06-21) on 2011-06-21. It moved from the RIPE NCC's unissued pool to an active registration dated around that day, so it appears to be newly issued by the RIPE NCC.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.

RDAP lookups

Not looked up. The tracker queries RDAP for changes as they're reported (on first sight, after 24 hours and after seven days); older changes aren't looked up because today's RDAP says nothing about the past.
