No transfer record matches. ARIN's statistics show it available on 2025-11-09 and assigned (dated 2025-11-10) on 2025-11-11. The tracker saw this range released from hold on 2025-08-19 (AS205663), so it appears to have been issued again from ARIN's pool.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-01-24. 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 2024-07-02) on 2025-07-23 and reserved on 2025-07-25. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed ASNs for 6 calendar months before reissuing them, so the estimated hold end is 2026-01-24. This does not confirm availability. Since mid-2024, ARIN has released many ASNs within two months, before the 6 calendar months were up, so the release can come sooner.

No transfer record matches. The RIPE NCC's statistics show it available on 2022-10-03 and allocated (dated 2022-10-04) on 2022-10-04. The tracker saw this range released from hold on 2022-10-03 (AS205663), so it appears to have been issued again from the RIPE NCC's pool. Another change to this range was reported the day before or after (2022-10-03: Released AS205663), so the before-and-after statistics may include it.

The RIPE NCC's statistics now list it as 'available'; reissue not confirmed

The RIPE NCC's statistics show it reserved on 2022-10-02 and available on 2022-10-03. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. The tracker saw it removed from registration on 2022-04-06, 180 days earlier. That is the RIPE NCC's own label: whether and when it is reissued is not confirmed. Another change to this range was reported the day before or after (2022-10-04: Added AS205663), so the before-and-after statistics may include it.

Removed from active registration. The tracker found it by comparing the RIPE NCC's daily statistics. The RIPE NCC's statistics show it allocated (dated 2017-06-29) on 2022-04-05 and reserved on 2022-04-06. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed ASNs for 180 days (six months), or longer while still routed, before reissuing them, so the estimated hold end is 2022-10-03. This does not confirm availability.

No transfer record matches. The RIPE NCC's statistics show it available on 2017-06-28 and allocated (dated 2017-06-29) on 2017-06-29. It moved from the RIPE NCC's unissued pool to an active registration dated around that day, so it appears to be newly issued by the RIPE NCC.

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.
