Thank you much for checking this. :)

Yeah, I don't use the "allow from" with a name anywhere that I can
recall, so I'd never run into this.  I'll have to try it on some older
Apache servers to see if it behaves differently.  It sure seems like a
bug somewhere.

RFC1912 (the text of which can be found in the caching-nameserver rpm
docs as rfc1912.txt, or at http://www.ietf.org/rfc/rfc1912.txt), says
this about localhost:

   The "localhost" address is a "special" address which always refers to
   the local host.  It should contain the following line:

           localhost.      IN      A       127.0.0.1

   The "127.0" file should contain the line:

           1    PTR     localhost.

   There has been some extensive discussion about whether or not to
   append the local domain to it.  The conclusion is that "localhost."
   would be the best solution.  The reasons given include:

      "localhost" by itself is used and expected to work in some
      systems.

      Translating 127.0.0.1 into "localhost.dom.ain" can cause some
      software to connect back to the loopback interface when it didn't
      want to because "localhost" is not equal to "localhost.dom.ain".

Now, I may very well be overlooking other relevant RFC's, but the
above reads to me like the default /etc/hosts entry which sets
127.0.0.1 to localhost.localdomain is causing the sort of problems
that they're warning about.  I don't know.  Maybe Apache tightened up
some of the rules used to process names used in "allow from"
directives.

I hadn't changed mine since sometime in 2001.  So I figured times must
have changed and I updated my zone info. :)

I have IPv6 disabled here, with neither any zones configured in DNS
nor entries in /etc/hosts.  Funny enough, one of the mantis
maintainers wondered if that might have some affect on things as well.

Thanks again for taking the time to test this out and confirm that it
breaks for you as well as it does for Charles and me.
