I have a sublevel domain name that is a branch off of one that is owned by DYN.com
In essence it is a host name under mine.nu that we use to do basic email services and web items. I am thinking of moving to webhostinghub, but need to know if I can still use that hostname and setup all of the dynamic dns items, to keep it working with the webhostinghub systems (so if the ip changes I am covered) or do I need to think of dropping my older name for a new domain.
We don't have any sort of dynamic DNS here, but you can certainly point specific DNS records over to the IP of the server you would be hosted on with us if you like. You would simply create an A record that points to the IP of the server that you are on. I am unsure as to how their interface works, but it should be a fairly simple process. Contacting them on how to point an A record would be your best option.
