Oh right then fair enough, Ive never used Debian before

Ubuntu/debian based systems unfortunately doesn't allow you to add one address and netmask it to cover a range. A rather large oversight in this day and age (thanks OVH!), hence the script.

Surly you only need to add the IP and the netmask once?

Having been given gazillions of ipv6 addresses with my server I thought it would be easy to assign them all to the server. Boy was I wrong

In that vein I wrote this bash script.

Hope it helps someone

A simple way to add a range of IP addresses:

addrange.sh

#!/bin/sh
if [ "$#" -ne "4" ]; then
        echo Usage:
        echo " $0 interface ip range netmask"
        echo " examples:"
        echo "  1) Assuming you want to bind the IP range 192.168.0.1..192.168.0.254 to eth0 with netmask 255.255.255.0:"
        echo "  $0 eth0 192.168.0. 1..254 255.255.255.0"
        echo "  2) Assuming you want to bind the IPv6 range 2001:41d0:1:5000::1-2001:41d0:1:5000::254 to eth0 with netmask /$
        echo "  $0 eth0 2001:41d0:1:5000:: 1..254 56"
else
        echo "Attempting to assign the IP range $2($3) to interface $1 with netmask $4"
        for ip in $(eval echo "{$3}"); do ifconfig -v $1 add $2$ip netmask $4; done
