On a recent RH system, "man 5 resolver" suggests that putting "options
inet6" into /etc/resolv.conf is what makes this happen ... if there is
such an entry on your system, try removing it. RH 8.0 is a good ways
back though, so read the local version of that man page before doing
anything with that config file.
I concur with Michael's previous suggestion that the best answer
is to fix the clearly-broken DNS environment you're dealing with.
It is no longer acceptable for anyone to be running nameservers
that have not heard of IPv6 --- unless it's for a network that
only contains clients that have not heard of IPv6, which yours
evidently is not. Have a word with your local network admin.
