No transfer record matches. ARIN's statistics show it available on 2025-12-09 and assigned (dated 2025-12-10) on 2025-12-11. The tracker saw this range released from hold on 2025-12-01 (AS31943-AS31946), so it appears to have been issued again from ARIN's pool.

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.
