No transfer record matches. The RIPE NCC's statistics show it reserved on 2021-11-11 and allocated (dated 2019-10-22) on 2021-11-12. The new registration isn't dated near that day, so the tracker can't tell whether this is a new issuance. Another change to this range was reported the day before or after (2021-11-11: Removed 194.41.36.0/23), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2022-05-10. 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 2019-10-22) on 2021-11-10 and reserved on 2021-11-11. Public sources do not distinguish a voluntary return, revocation, or reclamation. The RIPE NCC holds returned, revoked and reclaimed IPv4 space for 180 days (six months), or longer while still routed, before reissuing it, so the estimated hold end is 2022-05-10. This does not confirm availability. Another change to this range was reported the day before or after (2021-11-12: Added 194.41.36.0/23), so the before-and-after statistics may include it.

No transfer record matches. The RIPE NCC's statistics show it available on 2019-10-21 and allocated (dated 2019-10-22) on 2019-10-22. The tracker saw this range released from hold on 2015-02-16 (194.41.37.0/24), so it appears to have been issued again from the RIPE NCC's pool.

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.
