My mistake saying the IP address, it's because you type in ipconfig/all to get it, sorry if I confused things.

Regarding building a new machine, I had no problem changing my license over, I just asked Autodesk. They took my old and new MAC addresses and sent me a new license. But the dongle sounds like a good idea if you have a laptop that can run Maya, mine has trouble with MS Word!!.

Later,
