We set "HostnameLookups Off", yet we see many hostnames in both

This is causing huge problems because some of our clients have IP
addresses with no DNS entries, and the delay caused by the lookup is
enough to trigger a missed TCP/IP ACK packet on the client, resulting in
a five-second delay for every single GET request.
What, besides "HostnameLookups", can cause Apache to do a DNS lookup?
(And yes, I checked HostnameLookups VERY carefully. It is Off in
apache2.conf, and doesn't occur anywhere else in the entire disk drive.)

Craig,
Allow from <hostname> or <VirtualHost <hostname>:<port> > could cause that as
well.
Thanks, good point. But we don't do this anywhere. All of our virtual hosts are <VirtualHost
*:80> followed by a "ServerName" directive. And all of our "Allow from" are IP
addresses.
The odd thing is that only two customers have problems, but both of them are using
Windows XP. If we change to "Allow from all", their performance suddenly jumps
to normal.
Thanks,
Craig
