[erlang-questions] inet:gethostbyname issue [solved]

[Yogish Baliga]

Got the solution.

Have a inetrc file with the following content

{lookup, [native]}.

set the environment variable ERL_INETRC to the full path name of the inetrc file (default $HOME/.inetrc)

By default dns lookup is done in file, dns, native order

-- baliga
