how do FQDN

hey all,
i was going to install ISPconfig3 today, but i was prompted with a FQDN on install.. last time i did something like this i messed up my DNS really bad (check other posts)

So if i enter my domain name from godaddy... ns1.example.com (this is all setup in godaddy btw)

will i have to add anything in my server ( /etc.conf ) or anything like that?

if so what?? thanks all!

You can use any hostname for the server that you like as long as it exists in dns.
