Statistics
AS138510 reserved on 2026-10-07, allocated on 2026-10-08
Inventory
Likely issued from APNIC-controlled inventory

No transfer record matches. APNIC's statistics show it reserved on 2026-10-07 and allocated (dated 2026-10-07) on 2026-10-08. The tracker saw this range removed from registration on 2025-10-07 (AS138510), so it appears to have been issued again from APNIC's pool.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2026-10-07. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2018-12-18) on 2025-10-07 and available on 2025-10-08. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, but its statistics have released returned ASNs a year after the removal or later since 2014, so the tracker estimates the hold ends on 2026-10-07. That is what APNIC has done, not a rule it states. This does not confirm availability.

Statistics
AS138510 available on 2025-01-10, allocated on 2025-01-11
Inventory
No effect on APNIC applicant inventory

No transfer record matches. APNIC's statistics show it available on 2025-01-10 and allocated (dated 2018-12-18) on 2025-01-11. The tracker saw it removed from registration on 2024-12-30 (11 days earlier), and it is back with the same holder record it had before, so it went back to its previous holder rather than to a new one: most likely a suspension lifted, a reinstatement or a correction.

No transfer record matches. APNIC's statistics show it available on 2018-12-18 and allocated (dated 2018-12-18) on 2018-12-19. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

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.
