## Description

Netexpand will list every ip address in a given range, including broadcast and
network addresses.

An example usage for this program might be to use it to calculate every rule in
a firewall that uses slash notation for subnets (for an audit perhaps).


## Example

A simple example of calculating every ip address in the 127.0.0.1/16 range.

    $ netexpand 127.0.0.1/16
    127.0.0.1
    127.0.0.2
    127.0.0.3
    127.0.0.4
    127.0.0.5
    127.0.0.6
    127.0.0.7
    ...


Another slightly more complex example of using a bash for loop to feed ipv4
networks to netexpand for creating a complete list of all ips with rules in a
firewall.

    for i in $(cat fwnets.txt); do
      netexpand ${i}
    done
