If you plan to use "vanity" name servers (the same domain as the domain they are serving) then I will have to set that up for you manually... as CIRA will require IP addresses as well. You will also need two name servers. It's never a good idea to host a name server on the same IP address as the domain it is serving.
This is what you need because you want to host linuxottawa.ca on ns1.linuxottawa.ca.
