No transfer record matches. ARIN's statistics show it available on 2018-08-30 and assigned (dated 2018-08-31) on 2018-09-01. 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 ASN (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.
