I remember experimenting. I had to run a Bind in lwres mode on my workstation.
I could either query using DNS on port 53 or I could use a special port that
worked on localhost only.

I had to give it up because the lib did not look into /etc/hosts at all.
The memory footprint was horrible. Switching applications to use the lib was
horrible too.

Just for curiousity, djbdns has its own resolver lib too and "of course it is
much better than ..." and it too does not use /etc/hosts.
