I'm setting up a Domain Name System server through BIND9, under Debian Etch. It resides within a DMZ subnetwork which correcly recieves incoming port 53/udp-tcp requests forwarded by an iptables firewall. I've configured it to be the authoritative server for a domain I own. I asked the registrar to add to their NS records the public static IP that identifies my DNS server (which, as I have said, contains the zone data for my domain).
The registrar answers he can't, arguing he needs a registered name for that DNS server. So he's asking me to have what I'd like to achieve through my request.
What can I do?
