No transfer record matches. The RIPE NCC's statistics show it available on 2013-04-21 and allocated (dated 2000-11-08) on 2013-04-22. The new registration isn't dated near that day, so the tracker can't tell whether this is a new issuance.

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.
