netmask

netmask copied to clipboard

This is a handy tool for generating terse netmasks in several common formats. If you've ever maintained a firewall with more than a few rules in it, you might use netmask to clean up and generalize sloppy rules left by the netadmin before you. It will also convert netmasks from one format to another for the day you change your firewall software.

See the file INSTALL for building and installation instructions.
