netaddr Pythonic manipulation of IPv4, IPv6, CIDR, EUI and MAC network addresses a library providing Pythonic manipulation, validation and classification of common networking address notations, including :- * IPv4 * IPv6 * CIDR (Classless Inter-Domain Routing) * IEEE EUI-48, EUI-64 and MAC (Media Access Control) Each object represents an individual address or address range and behaves as you would expect when treated like standard Python types. For example :- If you call list() on a CIDR object, it provides an iterator yielding IP addresses. Calling len() returns the number of addresses found within the range. Indexing and/or slicing returns the addresses you'd expect. int() and hex() return the numerical value of an address in network byte order in the respective formats. http://code.google.com/p/netaddr/downloads/list David P.
