Every change the tracker has found, newest first. It covers ARIN from 2008-12-01, the RIPE NCC from 2010-04-23, APNIC from 2008-02-15, LACNIC from 2012-06-29 and AFRINIC from 2012-10-03.
The RIPE NCC's transfer log records a transfer from Xingchen (Guangdong) cloud computing co., LTD (RIPE NCC) to Rivulet Wireless Inc. (RIPE NCC) on 2022-07-06 19:00 UTC. The registration changed hands; it is not a new allocation from the RIPE NCC.

No transfer record matches. The RIPE NCC's statistics show it available on 2019-11-11 and allocated (dated 2019-11-12) on 2019-11-12. It moved from the RIPE NCC's unissued pool to an active registration dated around that day, so it appears to be newly issued by the RIPE NCC.

Possible future reissue candidate after hold
Hold estimate
Estimated hold end 2013-05-03. 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 assigned (dated 1996-02-13) on 2013-03-03 and not listed on 2013-03-05. (Until 2013-03-05, ARIN's statistics list only what's issued.) Being gone from ARIN's statistics entirely can also mean it moved to another registry. 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 2013-05-03. This does not confirm availability.

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.
