Hello:
While registering a domain name, what could I designate for the secondary DNS if I only use one server? Does the sec. DNS need to be dedicated?
Has anyone gotten around this in a creative way?
I'd be interested to hear how it's done.

You could try aliasing another ip address on the machine. (Use 2 ip's on 1 machine) and then run the secondary name server off of that machine. Something in that light. Or get a old 486 to just run the dns database and hook it up to your connection.
