No transfer record matches. APNIC's statistics show it reserved on 2016-01-08 and allocated (dated 2014-07-03) on 2016-01-09. The tracker saw it removed from registration on 2016-01-07 (1 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. Another change to this range was reported the day before or after (2016-01-07: Removed 150.242.104.0/22), so the before-and-after statistics may include it.

Hold estimate
Estimated hold end 2017-01-07. 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 2014-07-03) on 2016-01-07 and reserved on 2016-01-08. 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 2017-01-07. 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 (2016-01-08: Added 150.242.104.0/22), so the before-and-after statistics may include it.

No transfer record matches. APNIC's statistics show it available on 2014-07-03 and allocated (dated 2014-07-03) on 2014-07-04. It moved from APNIC's unissued pool to an active registration dated around that day, so it appears to be newly issued by APNIC.

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.
