How to bind a range of IP’s in Redhat based linux

How to bind a range of IP’s in Linux
This method is used by Redhat Linux based servers (Centos/RedhatEnterprise/FedoraCore).

Create a file called /etc/sysconfig/network-scripts/ifcfg-eth0-range0
And in the file place these 3 lines but change the IP’s to match YOUR assigned range.

## Start

# Example | IPADDR_START=67.18.333.440
# Example | IPADDR_END=67.18.333.444
# Example | CLONENUM_START=0

## END

The CLONENUM_START should be the number at which the alias interfaces should start. If you add your 5 IP’s to this server and then want to bind a second set of IP’s you create a second file named ‘ifcfg-eth0-range1’ and change the CLONENUM_START to match the last interface alias. IE ‘eth0:5’ = CLONENUM_START=5

After you have created the above file execute the command ‘service network restart’ and your IP’s will be all setup.

Please do not use this method of binding additional IPs if you are using Cpanel. Bind the IPs through the Cpanel interface.

How to bind a range of IP’s on BSD based hosts ( FreeBSD, OpenBSD )

First login to your FreeBSD host as a ‘non-root’ user. You should have an account in the ‘wheel’ group that you can do this with. Once you have logged in run the following commands to switch users to ‘root’

su –

The prompt should have a # in it now meaning you are the ‘root’ user.

Now run these commands.

ee /etc/rc.conf

Using – as an example

ifconfig_fxp0=”inet netmask″
ifconfig_fxp0_alias0=”inet netmask″
ifconfig_fxp0_alias1=”inet netmask″
ifconfig_fxp0_alias2=”inet netmask″
ifconfig_fxp0_alias3=”inet netmask″

Note that changes to the ‘_aliasNN’ and also the ‘netmask’ changes to ‘’ from ‘’. The IP’s will not work unless you use a ‘’ netmask for the alias IP’s.

Once you have added the enteries to your file you need to press ‘ESC’ and then select the ‘Save File’ option. You can then reboot the server and the IP’s will be bound and ready to use.

You can also use ‘ifconfig’ on the command line to add them without a reboot.

Please see the following man pages for more information.

man ifconfig
man rc.conf
man netstat
