You configure which name servers you want the world to query via your registrar (DNS delegation), but you don't actually need them to HOST the name server. If you have a managed server (I think mojo is all managed?) it would be better to let them handle DNS.
1. Mojo sets up name servers for your domain(s)
2. You log in to your registrar and change the name server entries to point at Mojo's name servers
