Likely issued from RIPE NCC-controlled inventory

No transfer record matches. The RIPE NCC's statistics show it available on 2012-04-24 and allocated (dated 2012-04-25) on 2012-04-25. 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.

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.
