How to have own nameserver using Digital Ocean's own nameserver
I read from here, http://digitalocean.uservoice.com/forums/136585-digital-ocean/suggestions/3637662-create-and-offer-anonymous-name-servers#comments, that you can have your own nameserver using DO's nameserver. How do I set this particularly in Centos 6.3 / Ubuntu 12.04? If i use my fancy nameserver with DO's IPs, can I delete the DNS entries in the DO dashboard or do I have to keep them so that the nameservers will resolve? I'm a new to this DNS thing really, please excuse me. Thanks.
