We recently signed up for the Comcast Business Class service.
The next step for us to get the service operational is to transfer our existing four domains from our old ISP to Comcast. We actually host all the servers/sites in our domains so it's just a matter of my either creating or importing the zones on Comcast and then my making the necessary IP address changes on our machines (we have five static IPs from Comcast). I've searched the help forums but didn't find anything that helps me with creating/importing DNS zones.
Any assistance with this inquiry would be greatly appreciated.
