Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2019-09-12. 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 2011-10-06) on 2019-03-11 and reserved on 2019-03-13. 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 2019-09-12. This does not confirm availability.

Inventory
Likely issued from ARIN-controlled inventory
No transfer record matches. ARIN's statistics show it not issued on 2011-10-05 and assigned (dated 2011-10-06) on 2011-10-07. (Until 2013-03-05, ARIN's statistics list only what's issued.) The tracker saw this range removed from registration on 2011-04-06 (2620:cd::/48), so it appears to have been issued again from ARIN's pool.

Classification history for this change (4 versions)
ARIN-Issued says "Remove", but ARIN's statistics show it not issued on 2011-10-05 and assigned (dated 2011-10-06) on 2011-10-07. (Until 2013-03-05, ARIN's statistics list only what's issued.) The registry's pool records from that time aren't public, so the tracker can't tell what was removed.

Transfer records
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.
