You have a couple of options.

The easiest, actually, so that you don't have to set subinterfaces, is to 
use the ip addr command:

ip addr add 172.53.0.1 dev eth0

Just put it into your /etc/rc.local file.

The other option is to go to /etc/sysconfig/network-scripts and create a 
file called ifcfg-lo:0, with the appropriate options.

I'd go with the first option, myself.
