This is simply a small tool that echoes the current IP address allocated. You can pick one and/or specify a favorite address to use.
Usage Example:
$ iptool # the tool itself
$ iptool --list # list IPs and interfaces
$ echo `myip` # a shorthand for getting the fav / first ip
$ ssh root@`myip` # example of usage
$ iptool --setvars # sets an env variable
$ ssh root@$PRIMEIP
$ ssh root@$_IP3
$ iptool --fav 4
$ iptool --fav `myip`
