Hold estimate
Estimated hold end 2019-06-22. 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 assigned (dated 2018-11-23) on 2018-12-23 and reserved on 2018-12-24. 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 2019-06-22. This does not confirm availability.

Transfer records

No transfer log has a transfer of any part of this IPv4 range.

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.
