2026-11-02ARIN+ AddApparent reissuance of previously removed resourceStrong inference
No transfer record matches. ARIN's statistics show it available on 2026-11-01 and allocated (dated 2026-11-02) on 2026-11-03. The tracker saw this range released from hold on 2025-12-30 (2600:2F00::-2600:2F0F:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF), so it appears to have been issued again from ARIN's pool.

2025-12-30ARIN− RemoveReleased from hold (ARIN lists it as 'available')Strong inference
ARIN's statistics now list it as 'available'; reissue not confirmed
ARIN's statistics show it reserved on 2025-12-29 and available on 2025-12-31. 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 2024-02-27, 672 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 2024-08-27. 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 2018-05-18) on 2024-02-26 and reserved on 2024-02-28. 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 2024-08-27. This does not confirm availability.

2018-05-18ARIN+ AddApparent new issuanceStrong inference
No transfer record matches. ARIN's statistics show it available on 2018-05-17 and allocated (dated 2018-05-18) on 2018-05-19. It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.
