Byron,
it does both. When/how it is used depends on /etc/host.conf, and
sometimes on the application.
I would guess that gethostbyname() and gethostbyaddr() will use
/etc/hosts depending on how /etc/host.conf is set.
But, "applications" like 'host' and 'nslookup' are dns specific, so they
will _NOT_ look at /etc/hosts.
I speak under correction, but this is my understanding :)

Patrick O'Reilly.
