In general, the Catch-22 is solved by allowing the parent zone to contain
"glue" A records for the nameservers in the child zone. How the necessary
IP address information is collected will vary from registrar to registrar,
but according to register.com's answer to the "How do I register a
DNS (Domain Name Server) on the Internet?" FAQ question: "In the event that
Domain Manager cannot translate the DNS name into an IP address, you will be
prompted to enter the IP address of the Domain Name Server you are attempting
to register".
