No transfer record matches. The RIPE NCC's statistics show it reserved on 2015-01-05 and allocated (dated 2015-01-06) on 2015-01-06. The tracker saw this range removed from registration on 2012-06-06 (AS51610), so it appears to have been issued again from the RIPE NCC's pool.

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 allocated (dated 2010-10-07) on 2012-06-05 and reserved on 2012-06-06. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC's current hold for ASNs applies to removals from 2014-03-26 on, and this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2010-10-07 and allocated (dated 2010-10-07) on 2010-10-08. 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 ASN (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.
