It's still supported by Red Hat, but the latest version is
bind-9.3.6-25.P1.el5_11.9.

Even on Red Hat Enterprise Linux 5, you can install the bind97-utils
package, which will give you a less ancient version.

(Obviously, moving to a newer version of the operating system is
strongly recommended at this point.)

Or at least use more realistic dig flags, such as “+norecurse +dnssec
+trace +all”.  In older versions, dig emulated stub resolver behavior
even with “+trace”, so the default flags were pretty useless for
testing.
