As the admin for W8CMN and 44.15/16 our PTR records are hosted on seven different
authoritative name servers in diverse areas and networks. BGP and IPIP included, if
somebody wants a PTR record make a request like normal, but we will not be allowing
transfers of zone files to any server not under our control. You are welcome to make PTR
queries like anybody else but no special zone transfers will be allowed.
