The most basic way would be:
- install a nameserver (BIND) somewhere, and make sure it's reachable on
tcp+udp port 53 from the entire world
- set up one or more zonefile, configure domain(s) in named.conf
- configure one or more external slave servers to _also_ be authoritative
for your domain(s), fetching updates from your master DNS server.
- make sure your slave server(s) can actually do a zone transfer from your
master. You might also want to prevent others (anyone except your slave
servers) from doing this.
- register/buy the domain name(s) if you haven't already done so.
- tell your registrar to configure your parent domain so it'll delegate
your domain to your nameservers.
