2013-05-20ARIN− RemoveChange to ARIN's own pool recordStrong inference
ARIN's statistics show it reserved on 2013-05-19 and assigned (dated 2013-05-20) on 2013-05-21. ARIN removed its own pool record for this range as part of issuing it: the same report adds 2620:5:4000::-2620:5:400F:FFFF:FFFF:FFFF:FFFF:FFFF. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2013-08-15. 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 2012-08-14) on 2013-02-14 and not issued on 2013-02-16. (Until 2013-03-05, ARIN's statistics list only what's issued.) 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 2013-08-15. This does not confirm availability.

2012-08-14ARIN+ AddApparent new issuanceStrong inference
No transfer record matches. ARIN's statistics show it not issued on 2012-08-13 and assigned (dated 2012-08-14) on 2012-08-15. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
