No transfer record matches. The RIPE NCC's statistics show it available on 2018-05-06 and allocated (dated 2018-05-07) on 2018-05-07. The tracker saw this range released from hold on 2014-11-17 (193.143.64.0 - 193.143.68.255), 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.
