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.
