/etc/hosts is not part of DNS. It is part of the name lookup procedure
used by gethostbyname(). So: squid is affected by /etc/hosts, but dig
and named are NOT, and will not be: they are specificly DNS tools.

My recommendation is to add a special .local zone to your named with
names host1.local etc with the private addresses. Then add local to the
_front_ of the search path in /etc/resolv.conf:

  search local your.normal.domain.here

Then using the short names should work.
