ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2025-12-17 and available on 2025-12-19. ARIN took it out of its reserved (held) records; its statistics now give it the status 'available'. The tracker saw it removed from registration on 2016-10-19, 3347 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2017-04-19. 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 allocated (dated 2011-06-02) on 2016-10-18 and reserved on 2016-10-20. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv6 space for 6 calendar months before reissuing it, so the estimated hold end is 2017-04-19. This does not confirm availability.

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.
