I have a 12 IPv4 addresses that I need to add to a CentOS 6.3 machine however those 12 IPs are spread out among 3 different subnets. I know how to add additional IPs when they are on the same subnet, but how can I do it with different subnets?
Is there a certain value to put in the ifcfg-eth0-range1 file such as GATEWAY=X.X.X.X?
Thanks
