So to clarify, how many different things which need to be handled are there? Items: 1 IP address -- a 32 bit (IPv4) or 128 bit (IPv6) number 2 Netmask -- a bit mask of the form 111..100..0 3 Network address -- the lowest address in a network, and equal to (defined by?) the bitwise-AND of any address in the network with the network's netmask 4 Host address -- the part of the IP address that is not masked by the netmask 5 Broadcast address -- the highest address in a IPv4 network Containers: 6 Network -- a range of IP address Have I missed anything or got anything wrong? -- Steven D'Aprano _______________________________________________ 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
