Please update the table above if you are going to announce a new prefix, and give a heads up on the mailing list. This gives the rest of us time to update our filters.

Allocate your subnet here, then add a zonefile to the 020_dns repository so reverse and forward dns will work, alternatively setup your own authoritative dns for the forward and reverse zones, and add it to the forwarders file in 020_dns repo
