I know there are a few of them, but I'd prefer to use the system's own
resolver. A few reasons that I can think of:

 - do external dns resolver libraries support /etc/hosts?
 - or are there some other site-specific features? dnssec, etc.?
 - DNS has had security problems recently. Upgrading OS's own resolver
is easier than upgrading all software that have their internal
resolvers.
