This package is deprecated; please use NetCIDR instead (http://cheeseshop.python.org/pypi/NetCIDR).
There are five major chunks of functionality to this library:
* create CIDR addresses for hosts and net blocks
* get node counts for any given netblock
* get ranges of addresses for net blocks
* create collections of networks (list subclass)
* determine if a CIDR address is in a given network or set of networks
