Netscape has its own, internal address cache (so that when a page contains
image and/or frame links to other pages on the same server, it doesn't have
to do zillions of DNS lookups).  I think it caches addresses for 5 minutes
by default.

I'm happy to learn that it does failover.  Given that it does, it's not too
surprising that the address it caches is the one that it actually used.
