To start with, you need a nameserver.
If you have a nameserver that you wish to use with your new domain, please specify it during the order process. If you do not, we will make use of our default nameservers:
ns1.netorbmedia.com
ns2.netorbmedia.com
ns3.netorbmedia.com
If you use our nameservers, you would have to depend on us to update your zone records: A, CNAME, MX, etc (by the way, if you do not know what these mean, then you definitely need us to do it for you!)
If you do not have your own nameservers but understand the nitty-gritty of zone records, then we can offer you a control panel from where you can manage your records, using our own nameservers. We have it over at http://dns.netorbmedia.com.
