I thought that someone mentioned that the new cox setup changes from a
hostname authentication to a mac address authentication to get dhcp
service. This would suggest that in the conversion process, the first
assignment with your cxXXXXXXX-x hostname captured the mac address of
your network interface and locked it down. Thus switching to another NIC
(computer/router device) would mean that it can't capture an ip address
unless you call customer support and they release it.
If this is true, and I haven't verified it, this would make it a bad
idea to use a windows computer to get the ip address from the dhcp
server and then switching it out for a linux box.
