IPADDR_START

cd /etc/sysconfig/network-scripts

ls ifcfg-eth0-range*

If you already have a range file, you will need to create a new one for the new range of IPs you are adding, eg ‘nano ifcfg-eth1-range1` .  If you have one named range1, name the next range2 and so on.

ifcfg-eth0-range1

Place the following text in the file:

IPADDR_START=192.168.0.10
IPADDR_END=192.168.0.110
CLONENUM_START=0

Note: CLONENUM_START defines where the alias will start.  If this is the second range file, you will need to set CLONENUM_START to a value higher than the number of IP addresses assigned.  To check what you currently have used, you can run ‘ifconfig –a | grep eth0’.  This will list devices such as eth0:0, eth0:1, eth0:2, and so on.  If you are currently using upto eth0:16, you will need to set CLONENUM_START to 17 to assign the IPs correctly.
