Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.
2014-02-04ARIN+ AddApparent reissuance of previously removed resourceStrong inference
No transfer record matches. ARIN's statistics show it available on 2014-02-03 and allocated (dated 2014-02-04) on 2014-02-05. The tracker saw this range released from hold on 2014-01-28 (2604:8180::-2604:8180:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so it appears to have been issued again from ARIN's pool.

ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2014-01-27 and available on 2014-01-29. 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 2013-10-28, 92 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 2014-04-28. 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 2013-03-01) on 2013-10-27 and reserved on 2013-10-29. 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 2014-04-28. This does not confirm availability.

2013-03-01ARIN+ AddApparent new issuanceStrong inference
No transfer record matches. ARIN's statistics show it not issued on 2013-02-28 and allocated (dated 2013-03-01) on 2013-03-02. (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.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv6 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.
