[44net] How to admin 44.151 ?!

Hello, here are my practical questions: . How can a French radio amateur request for an IP 44.151 /32 for example ? . Until now, as administrator, I managed the numbering, but I don't know how to do it now. . I used to create DNS in this sub-domain with direct-to-server commands, but now I don't know how. It's still a big mystery. Thank's. Ludovic - F5PBG - Subnet 44.151 in distress... 😉
