No transfer record matches. ARIN's statistics show it reserved on 2026-10-05 and allocated (dated 2026-10-06) on 2026-10-07. The tracker saw this range released from hold on 2026-10-02 (63.141.38.0-63.141.38.255), so it appears to have been issued again from ARIN's pool.

ARIN's statistics show it reserved on 2026-10-05 and allocated (dated 2026-10-06) on 2026-10-07. ARIN removed its own pool record for this range as part of issuing it: the same report adds 63.141.38.0-63.141.38.255. The issuance is explained on that line.

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.
