As an addendum to Alexander's advice, you can also take a read 
through the comments in the file:

/etc/sysconfig/network-scripts/ifup-aliases


For example, I use the file:

ifcfg-eth0-range0


like so:

============
IPADDR_START=192.168.1.42
IPADDR_END=192.168.1.180
CLONENUM_START=0
NO_ALIASROUTING=yes
============

to create aliases for all addresses from ...42 to ...180 in a single 
file which will be handy if you plan to expand your alias usage in 
the future as you won't have to create individual files.
