Args: address: A string or integer representing the IP [& network]. '192.0.2.0/24' '192.0.2.0/255.255.255.0' '192.0.0.2/0.0.0.255' are all functionally the same in IPv4. Similarly, '192.0.2.1' '192.0.2.1/255.255.255.255' '192.0.2.1/32' are also functionally equivalent. That is to say, failing to provide a subnetmask will create an object with a mask of /32. If the mask (portion after the / in the argument) is given in dotted quad form, it is treated as a netmask if it starts with a non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it starts with a zero field (e.g. 0.255.255.255 == /8), with the single exception of an all-zero mask which is treated as a netmask == /0. If no mask is given, a default of /32 is used. Additionally, an integer can be passed, so IPv4Network('192.0.2.1') == IPv4Network(3221225985) or, more generally IPv4Interface(int(IPv4Interface('192.0.2.1'))) == IPv4Interface('192.0.2.1') Raises: AddressValueError: If ipaddress isn't a valid IPv4 address.

Args: address: A string or integer representing the IPv6 network or the IP and prefix/netmask. '2001:db8::/128' '2001:db8:0000:0000:0000:0000:0000:0000/128' '2001:db8::' are all functionally the same in IPv6. That is to say, failing to provide a subnetmask will create an object with a mask of /128. Additionally, an integer can be passed, so IPv6Network('2001:db8::') == IPv6Network(42540766411282592856903984951653826560) or, more generally IPv6Network(int(IPv6Network('2001:db8::'))) == IPv6Network('2001:db8::') strict: A boolean. If true, ensure that we have been passed A true network address, eg, 2001:db8::1000/124 and not an IP address on a network, eg, 2001:db8::1/124. Raises: AddressValueError: If address isn't a valid IPv6 address. NetmaskValueError: If the netmask isn't valid for an IPv6 address. ValueError: If strict was True and a network address was not supplied.

Note that the site-local address space has been deprecated by RFC 3879. Use is_private to test if this address is in the space of unique local addresses as defined by RFC 4193.
