The iprange command is quite useful for working with prefix lists. Aggregating lists, removing duplicates etc.
When available, it is used by the WaterByWind provided edgeos-bl-mgmt project to aggregate blacklists.
It is possible that other users will want to use that script, or have other network lists they which to aggregate on device.
Given that the iprange Debian package is 31K and it is a network related package, I hope it could be included.
