Hold estimate
Estimated hold end 2016-02-06. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it assigned (dated 2013-07-25) on 2015-12-07 and reserved on 2015-12-09. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2016-02-06. This does not confirm availability.

No transfer record matches. ARIN's statistics show it available on 2013-07-24 and assigned (dated 2013-07-25) on 2013-07-26. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
