No transfer record matches. The RIPE NCC's statistics show it reserved on 2018-08-20 and allocated (dated 2006-08-15) on 2018-08-21. The new registration isn't dated near that day, so the tracker can't tell whether this is a new issuance.

Hold estimate
Estimated hold end 2016-04-12. 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 2006-08-15) on 2015-10-14 and reserved on 2015-10-15. 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 2016-04-12. This does not confirm availability.

No transfer log has a transfer of any part of this ASN.
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.
