123.34.56.78 is a valid IP address, per se...

Nice thing about the RH config file naming, you don't have the name the file
after the device. RH network scripts use the DEVICE= line to determine what
device to change, so you could call the file ifcfg-domain and then invoke it
with "ifup domain" and RH will know to use that file and device eth0:5.

This is useful as you can then name the files to help you remember what they are
for (such as if you have virtual adapters for FTP, HTTP, IRC, etc...).
