The absolute simplest way to get things running again is to install
"bind" from the installation media (if it isn't already there), don't
configure it at all, but just go ahead and start the "named" service
it will install. This will get you a local DNS server that talks
directly to the root DNS servers, bypassing your ISP's DNS servers
completely. Then point your /etc/resolv.conf file to "nameserver 127.0.0.1"
and you should be working well enough to get to sites where you can learn
how to config bind as a caching server instead, like these:

You moght also need to add the line

OPTIONS="-4"

to the /etc/sysconfig/named file to tell it only do IPv4 names.
