what is connection specific dns?
For example you have a two NIC computer and one is hooked to the SBCGLOBAL.NET network and the other goes to a private family network that you called FAMILY.LOCAL. You would set up on the NICs the names of the Networks. In my ecample your computer is called computer1. So from the SBCGLOBAL network your FQDN would be computer1.sbcglobal.net and on your family network your computer would be computer1.family.local. In short the Connection-Specfic DNS suffix is the network name that a NIC (Network.Interface Card) is hooked to. Source(s):
