The !ipaddress module provides factory functions to conveniently create IP addresses, networks and interfaces Return an IPv4Address or IPv6Address object depending on the IP address passed as argument. Either IPv4 or IPv6 addresses may be supplied; integers less than 232 will be considered to be IPv4 by default. A ValueError is raised if address does not represent a valid IPv4 or IPv6 address. >>> ipaddress.ip_address('192.168.0.1') IPv4Address('192.168.0.1') >>> ipaddress.ip_address('2001:db8::') IPv6Address('2001:db8::') Return an IPv4Network or IPv6Network object depending on the IP address passed as argument. address is a string or integer representing the IP network. Either IPv4 or IPv6 networks may be supplied; integers less than 232 will be considered to be IPv4 by default. strict is passed to IPv4Network or IPv6Network constructor. A ValueError is raised if address does not represent a valid IPv4 or IPv6 address, or if the network has host bits set. >>> ipaddress.ip_network('192.168.0.0/28') IPv4Network('192.168.0.0/28') Return an IPv4Interface or IPv6Interface object depending on the IP address passed as argument. address is a string or integer representing the IP address. Either IPv4 or IPv6 addresses may be supplied; integers less than 232 will be considered to be IPv4 by default. A ValueError is raised if address does not represent a valid IPv4 or IPv6 address. One downside of these convenience functions is that the need to handle both IPv4 and IPv6 formats means that error messages provide minimal information on the precise error, as the functions don't know whether the IPv4 or IPv6 format was intended. More detailed error reporting can be obtained by calling the appropriate version specific class constructors directly. Attribution: Adapted from Python Documentation under PSF-2.0.
