The inet_network() routine converts a string representing an IPv4 Internet address
(for example, “127.0.0.1”)
into a numeric Internet network number.
All Internet addresses are returned in network order
(bytes are ordered from left to right).
All network numbers and local address parts are returned as machine-format integer values.
For more information on Internet addresses, see
inet_net_ntop().
An Internet network number, or INADDR_NONE if an error occurs.
