No transfer record matches. The RIPE NCC's statistics show it available on 2011-05-19 and allocated (dated 2011-05-19) on 2011-05-20. The tracker saw this range removed from registration on 2011-03-08 (176.0.0.0/10), so it appears to have been issued again from the RIPE NCC's pool.

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.
