I know how to create records but how do I go about setting up two name servers.

say if I wanted to create

ns1.funs.co.uk
ns2.funs.co.uk

do they both have to have different ip's or is the differnet ip thing not totally essential.

if I set up the name servers, like that how woudl I do that on a raq4i and woudl I have t create some dns records prior to getting the funs.co.uk domain pointed to the two name servers I just created or not.

any help please on how to get my domain to use the dns on the server woudl be very helpful.
