Or, to put it another way, given an arbitrary host in a network (e.g. your own machine or the default gateway) and the netmask for that network, calculate the network address.
Some people have claimed that the gateway address of a network isn't necessarily the zero address in that network. If that's true, then you *can't* calculate the network address from a host address and a netmask -- there isn't enough information. Furthermore, an IPNetwork object needs to be able to represent a network address whose address part contains bits that aren't in the mask. -- Greg _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
