Sorry, but I doubt anyone was able to understand your question.
At least I wasn't. You may try to clarify what you want to do and
what is your question.

Just in case, parameters of the "resolver" directive specify DNS
servers to use, and it's completely unrelated to system
gethostbyaddr(), resolv.conf and /etc/hosts. For an example of
how to use resolver from an nginx module take a look at
ngx_http_upstream.c and/or ngx_mail_smtp_handler.c.
