How to create a range of ip addresses on ethx. Create a range file in /etc/sysconfig/network-scripts
E.Q.
ifcfg-eth0-range1
DEVICE=eth0 BOOTPROTO=static HWADDR=00:04:75:D4:C8:F9 IPADDR_START=192.168.0.6 IPADDR_END=192.168.0.10 CLONENUM_START=1 NETMASK=255.255.255.0 ONBOOT=yes TYPE=Ethernet
CLONENUM_START -- interface clone number to start using for this range. # eg "1"
Which would start at eth0:1
