Damn... when I'd searched I didn't find anything, so I reinvented the wheel in

http://www.sil-tec.gr/~tzot/python/IPv4_Utils-0.35.linux-i586.tar.gz

It seems that ipv4 from pynms almost matches the functionality of my module,
except for a function (included_nets): given two hosts/nets, find the minimal
set of networks that include both hosts/nets.  Just in case Dan needs such a
function.

netmask arithmetic?

2005-02-25 Thread Dan Stromberg

Before I go and reinvent the wheel, does anyone already have python code
that can do netmask arithmetic - for example, determining if a list of
hostnames are on subnets described by a list of networks+netmasks like:

128.200.34.0/24
128.195.16.128/25

...and so on?

Thanks!
