Well is it the right IP address?

You can check with dig easy enough, who needs websites ;)

"4.9.8-REL"    

You don't appear to have an entry for the IP addresses of either
name server in the zone file. Adding those two as A records will
help things enormously.

It is vaguely possible that named version is coming from your
firewall. More likely is the IP address is wrong, or you are
running the wrong version of named for some reason, usually
because you have a Redhat version in /sbin/named and the ISC
version in /usr/local/sbin/named, so some such confusion.
