DIAGNOSTICS
The constant INADDR_NONE is returned by inet_addr() and inet_network()
for malformed requests.

byteorder(3), gethostbyname(3), getnetent(3), inet_net(3), hosts(5),
networks(5)
STANDARDS
The inet_ntop and inet_pton functions conforms to the IETF IPv6 BSD API
and address formatting specifications.
Note that inet_pton does not
accept 1-, 2-, or 3-part dotted addresses; all four parts must be speci-
fied.
This is a narrower input set than that accepted by inet_aton.
HISTORY
The inet_addr, inet_network, inet_makeaddr, inet_lnaof and inet_netof
functions appeared in 4.2BSD.
The inet_aton and inet_ntoa functions
appeared in 4.3BSD.
The inet_pton and inet_ntop functions appeared in
BIND 4.9.4.
BUGS
The value INADDR_NONE (0xffffffff) is a valid broadcast address, but
inet_addr() cannot return that value without indicating failure.
Also,
inet_addr() should have been designed to return a struct in_addr.
The
newer inet_aton() function does not share these problems, and almost all
existing code should be modified to use inet_aton() instead.
The problem of host byte ordering versus network byte ordering is confus-
ing.
The string returned by inet_ntoa() resides in a static memory area.
