Possible future reissue candidate after hold
Removed from active registration. The tracker found it by comparing RIPE NCC's daily statistics. RIPE NCC's statistics show it allocated (dated 2026-05-22) on 2026-07-20 and reserved on 2026-07-21. Public sources do not distinguish a voluntary return, revocation, or reclamation. RIPE NCC publishes no fixed period for which it holds returned ASNs before reissuing them, so the tracker gives no estimate. This does not confirm availability.

Likely issued from RIPE NCC-controlled inventory
No transfer record matches. RIPE NCC's statistics show it available on 2026-05-21 and allocated (dated 2026-05-22) on 2026-05-22. The tracker saw this range released from hold on 2026-02-28 (AS197331), so it appears to have been issued again from RIPE NCC's pool.

RIPE NCC's statistics now list it as 'available'; reissue not confirmed
RIPE NCC's statistics show it reserved on 2026-02-27 and available on 2026-02-28. RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. That is RIPE NCC's own label: whether and when it is reissued is not confirmed.

Every record in the ARIN and RIPE NCC transfer logs that moved any part of this ASN (ARIN's go back to 2009, the RIPE NCC's to 2012). A transfer between two registries is in both logs.
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.
