Timeline (4)

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.

2016-08-23 ARIN Not in ARIN-Issued Removed (return, revocation or reclamation not publicly distinguishable) Strong inference

Inventory: Possible future reissue candidate after hold
Hold estimate: Estimated hold end 2017-02-23. 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 2014-03-31) on 2016-08-22 and reserved on 2016-08-24. 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 2017-02-23. This does not confirm availability.

2014-03-31 ARIN + Add Apparent reissuance of previously removed resource Strong inference

ARIN-Issued: Add 2604:ED00::-2604:ED00:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF
Inventory: Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2014-03-30 and allocated (dated 2014-03-31) on 2014-04-01. The tracker saw this range removed from registration on 2013-12-27 (2604:ed00::/32), so it appears to have been issued again from ARIN's pool.

ARIN-Issued: Remove 2604:ED00::-2604:ED00:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF
Inventory: Part of the issuance reported the same day

ARIN's statistics show it reserved on 2014-03-30 and allocated (dated 2014-03-31) on 2014-04-01. ARIN removed its own pool record for this range as part of issuing it: the same report adds 2604:ED00::-2604:ED00:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF. The issuance is explained on that line.

Hold estimate: Estimated hold end 2014-06-27. 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 2011-05-24) on 2013-12-26 and reserved on 2013-12-28. Public sources do not distinguish a voluntary return, revocation, or reclamation.

No transfer log has a transfer of any part of this IPv6 range.

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.
