I am trying to find a way to convert a ip address to a 32 bit integer in Ruby for a puppet template.

This is how I did the conversion in bash.

root@ubuntu-server2:~# cat test.sh 
#!/bin/bash

#eth0 address is 10.0.2.15
privip=`ifconfig eth0 | grep "inet addr:" | cut -d : -f 2 | cut -d " " -f 1` ;

echo "Private IP: ${privip}" ;

# Turn it into unsigned 32-bit integer

ipiter=3 ;

for ipoctet in `echo ${privip} | tr . " "` ;
    do
    ipint=$(( ipint + ( ipoctet * 256 ** ipiter-- ) )) ;
    done ;

echo "Private IP int32: ${ipint}" ;

.

root@ubuntu-server2:~# bash test.sh 
Private IP: 10.0.2.15
Private IP int32: 167772687

Any help would be greatly appreciated.
