APNIC's transfer log records a transfer from BESTA-3 (ARIN) to China Unicom (Hong Kong) Operations Limited (APNIC) on 2023-10-10 05:39 UTC: it came to APNIC from ARIN. It was already issued by another registry, so this is not a new issuance.

No effect on ARIN applicant inventory

No transfer record matches. ARIN's statistics show it reserved on 2023-02-15 and allocated (dated 2023-02-16) on 2023-02-17. The tracker saw it removed from registration on 2022-07-04 (227 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.

Part of the issuance reported the same day

ARIN's statistics show it reserved on 2023-02-15 and allocated (dated 2023-02-16) on 2023-02-17. ARIN removed its own pool record for this range as part of issuing it: the same report adds 204.110.8.0-204.110.15.255. The issuance is explained on that line.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2022-09-02. Possible reissue candidate after this date; not confirmed available.

Removed from active registration. ARIN-Issued didn't list this; the tracker found it by comparing ARIN's daily statistics. ARIN's statistics show it allocated (dated 2009-02-05) on 2022-07-03 and reserved on 2022-07-05. Public sources do not distinguish a voluntary return, revocation, or reclamation. ARIN holds returned, revoked and reclaimed IPv4 space for 60 days before reissuing it, so the estimated hold end is 2022-09-02. This does not confirm availability.

ARIN-Issued
Add 204.110.8.0-204.110.15.255
Inventory
Likely issued from ARIN-controlled inventory

No transfer record matches. ARIN's statistics show it not issued on 2009-02-04 and allocated (dated 2009-02-05) on 2009-02-06. (Until 2013-03-05, ARIN's statistics list only what's issued.) It moved from ARIN's unissued pool to an active registration dated around the report, so it appears to be newly issued by ARIN.

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.
