No transfer record matches. APNIC's statistics show it available on 2016-07-08 and allocated (dated 2016-07-08) on 2016-07-09. The tracker saw this range removed from registration on 2011-03-31 (AS4801), so it appears to have been issued again from APNIC's pool.

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 2010-01-25) on 2011-03-31 and available on 2011-04-01. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

No transfer record matches. APNIC's statistics show it not listed on 2010-01-25 and allocated (dated 2010-01-25) on 2010-01-26. It wasn't in APNIC's statistics before, so it wasn't APNIC's unissued inventory; it may have come from another registry in a transfer not yet in the log.

Removed from active registration. The tracker found it by comparing APNIC's daily statistics. APNIC's statistics show it allocated (dated 1996-12-19) on 2008-09-30 and not listed on 2008-10-01. Being gone from APNIC's statistics entirely can also mean it moved to another registry. Public sources do not distinguish a voluntary return, revocation, or reclamation. APNIC publishes no hold period, and its statistics show a steady one (a year) only for removals from 2014-07-01 on; this one came earlier, so the tracker gives no estimate. This does not confirm availability.

Transfer records
No transfer log has a transfer of any part of this ASN.
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.
