To determine the appropriate network address.

The interpretation is similar to an integer address.Ī two-tuple of an address description and a netmask, where the addressĭescription is either a string, a 32-bits integer, a 4-bytes packed Single-address network, with the network address being address andĪn integer packed into a bytes object of length 4, big-endian. If no mask is provided,įor example, the following address specifications are equivalent:ġ92.168.1.0/24, 192.168.1.0/255.255.255.0 andĪn integer that fits into 32 bits.

Interpreted as a net mask if it starts with a non-zero field, or as a The IP address is the network address, and the maskĬan be either a single number, which means it’s a prefix, or a string address can be one of the following:Ī string consisting of an IP address and an optional mask, separated byĪ slash ( /). IPv4Network ( address, strict = True ) ¶Ĭonstruct an IPv4 network definition. Network objects are hashable, so they can be used as keys inĭictionaries. So to avoid duplication they are only documented for IPv4Network.
