No transfer record matches. APNIC's statistics show it available on 2026-05-11 and allocated (dated 2026-05-11) on 2026-05-12. The tracker saw this range released from hold on 2026-05-10 (AS153874-AS153875), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2026-05-10: Released AS153874-AS153875), so the before-and-after statistics may include it.

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.
