Foo is an IP address.

Prior to this experience, I would have said, yes.  But now I'm not so sure.

I'm pretty sure.  The entry is not in the zone file and a dig on the
DNS machine itself does not return an answer for Bar but does for
other names.  I get the same result using a RHEL machine and even the
Ubuntu machine.  It just takes several minutes (or a reboot) on the
Ubuntu machine.

Will do.
