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

The RIPE NCC's statistics show it reserved on 2012-09-09 and available on 2012-09-10. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2012-08-28, 13 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2012-09-11: Added 193.222.48.0/23; 2012-09-11: Added 193.222.50.0/24; 2012-09-11: Added 193.222.51.0/24), so the before-and-after statistics may include it.

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 2011-10-31) on 2012-08-27 and reserved on 2012-08-28. 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 reserved on 2011-10-30 and assigned (dated 2011-10-31) on 2011-10-31. The tracker saw this range removed from registration on 2011-08-02 (193.222.48.0 - 193.222.58.255), so it appears to have been issued again from the RIPE NCC's pool.

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.
