The RIPE NCC's transfer log records a transfer from an unnamed organization (ARIN) to Krixe Pte. Ltd. (RIPE NCC) on 2025-12-23 19:00 UTC: it came to the RIPE NCC from ARIN. It was already issued by another registry, so this is not a new issuance.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2022-01-22. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2017-02-21) on 2021-11-22 and reserved on 2021-11-24. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2022-01-22. This does not confirm availability.

Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it reserved on 2017-02-20 and allocated (dated 2017-02-21) on 2017-02-22. The tracker saw this range removed from registration on 2014-12-09 (207.189.0.0/19), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2017-02-20 and allocated (dated 2017-02-21) on 2017-02-22. ARIN removed its own pool record for this range as part of issuing it: the same report adds 207.189.0.0-207.189.31.255. The issuance is explained on that line.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics.

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.
