Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2025-10-27) on 2025-10-28 and available on 2025-10-29. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, but its statistics have released returned IPv4 space a year after the removal or later since 2014, so the tracker estimates the hold ends on 2026-10-28. That is what APNIC has done, not a rule it states. This does not confirm availability. Another change to this range was reported the day before or after (2025-10-27: Added 138.252.99.0/24), so the before-and-after statistics may include it.

Likely issued from APNIC-controlled inventory
No transfer record matches. APNIC's statistics show it available on 2025-10-27 and allocated (dated 2025-10-27) on 2025-10-28. The tracker saw this range released from hold on 2021-08-25 (138.252.0.0/16), so it appears to have been issued again from APNIC's pool. Another change to this range was reported the day before or after (2025-10-28: Removed 138.252.99.0/24), so the before-and-after statistics may include it.

Every record in the ARIN, RIPE NCC, APNIC, LACNIC and AFRINIC transfer logs that moved any part of this IPv4 range (ARIN's from 2009, the RIPE NCC's from 2012, APNIC's from 2010, LACNIC's from 2016, AFRINIC's from 2018). A transfer between two registries is in both logs.
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.
