[lwip-devel] [bug #26657] DNS, if host name is "localhost", result is error.

[Simon Goldschmidt]

Follow-up Comment #2, bug #26657 (project lwip):

Seems like hanhui is correct:

Excerpt from gethostbyaddr description of opengroup:
"The addr argument of gethostbyaddr() shall be an in_addr structure when type
is AF_INET. It contains a binary format (that is, not null-terminated) address
in network byte order. The gethostbyaddr() function is not guaranteed to
return addresses of address families other than AF_INET, even when such
addresses exist in the database."

And after all, the addresses we return from real lookups are also in network
byte order. This also has to be adjusted in dns_gethostbyname().
