Hold estimate
Estimated hold end 2026-06-27. Possible reissue candidate after this date; not confirmed available.

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 2016-02-18) on 2025-12-28 and reserved on 2025-12-29. 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 2026-06-27. This does not confirm availability.

Likely issued from RIPE NCC-controlled inventory

No transfer record matches. The RIPE NCC's statistics show it available on 2016-02-17 and allocated (dated 2016-02-18) on 2016-02-18. 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. Another change to this range was reported the day before or after (2016-02-17: Released AS204117), 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 2016-02-16 and available on 2016-02-17. The RIPE NCC moved it from its reserved (held) records to the status it calls 'available'. 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 (2016-02-18: Added AS204117), so the before-and-after statistics may include it.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this ASN (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). 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.
