<heading>I'm in <tt>foo.bar.edu</tt>, and I can no longer reach hosts in <tt>bar.edu</tt> by their short names</heading>
<p>
The current version of <em>BIND</em> that ships with FreeBSD
does no longer provide default abbreviations for non-fully
qualified domain names other than the domain you are in.
So an unqualified host <tt>mumble</tt> must either be found
as <tt>mumble.foo.bar.edu</tt>, or it will be searched for
in the root domain.
<p>
This is different from the previous behaviour, where the
search did continue across <tt>mumble.bar.edu</tt>, and
<tt>mumble.edu</tt>. Have a look at RFC 1535 for why this
has been considered bad practice and even a security hole.
<p>
As a good workaround, you can place the line
<p><tt>
search foo.bar.edu bar.edu
</tt><p>
instead of the previous
<p><tt>
domain foo.bar.edu
</tt><p>
into your <tt>/etc/resolv.conf</tt>. However, make sure
that the search order does not go beyond the ``boundary
between local and public administration'', as RFC 1535
calls ist.
