CentOS - Nov 2011 - binding additional IP addresses to centos6 on one interface

I know this was discussed before, and I have seen a million ways of 
doing this via online docs. I have a quick question that hopefully the 
community can help me out with

I am trying to add a block of 10 IP addresses. Rather then create 10 
different alias files, I want to use the RANGE file.

Docs say to use the following format:
IPADDR_START=x.x.x.x
IPADDR_END=x.x.x.x
CLONENUM_START=0

If the IP's that are given to you are on a completely seperate gateway / 
netmask, how would you enter it into this file? Is it necessary? Please 
advise.

who needs ranges?
configure what you need!

cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
IPADDR=10.0.0.6
GATEWAY=10.0.0.1
NETMASK=255.255.255.0
ONBOOT=yes
BOOTPROTO=static
TYPE=Ethernet
MODE=Managed
IPV6INIT=no
NM_CONTROLLED=no
USERCTL=no
MTU=1500

cat /etc/sysconfig/network-scripts/ifcfg-eth0:1
DEVICE=eth0:1
IPADDR=10.0.0.7
ONPARENT=yes

cat /etc/sysconfig/network-scripts/ifcfg-eth0:2
DEVICE=eth0:2
IPADDR=10.0.0.5
ONPARENT=yes

Reindl,

A block of 10 IPV4 is not a lot, and they will all eventually be used. 
My question is, my server IP is 66.80.x.x and my additional IPS are in 
the 50.7.x.x range using a netmask of 255.255.255.248.

Can the netmask be written in the range file like it is in the ifcfg-eth0:0?
