2014-07-22ARIN+ AddApparent reissuance of previously removed resourceObserved only
No transfer record matches. ARIN's statistics show it reserved on 2014-07-21 and allocated (dated 2014-07-22) on 2014-07-23. The tracker saw this range released from hold on 2014-07-21 (2604:9580::-2604:9580:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so it appears to have been issued again from ARIN's pool. Another change to this range was reported the day before or after (2014-07-21: Remove 2604:9580::-2604:9580:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so the before-and-after statistics may include it.

2014-07-21ARIN− RemoveReleased from hold (ARIN lists it as 'available')Observed only
ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2014-07-20 and available on 2014-07-22. 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 2014-05-13, 69 days earlier. That is ARIN's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2014-07-22: Add 2604:9580::-2604:9580:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2014-11-13. 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 2013-03-21) on 2014-05-12 and reserved on 2014-05-14. 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 2014-11-13. This does not confirm availability.

2013-03-21ARIN+ AddApparent new issuanceStrong inference
No transfer record matches. ARIN's statistics show it available on 2013-03-20 and allocated (dated 2013-03-21) on 2013-03-22. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
