I should have said, "It attempts hostname resolution mehod first," which is
more descriptive.
And yes, the hosts file will be checked prior to DNS.
However funny thing about the local cache, it checks that first because when
you create an entry in the hosts file, it automatically gets loaded into
cache. I think it's redundant that it checks the hosts file afterwards,
since it's assumed that whatever is in hosts, would have been autoloaded
into cache anyway.
