Here at rmkhome.com I'm runnig 8.2.3 on SunOS 4.1.4 ( soon to be
upgraded to NetBSD 1.5 :)

Here is what I get:

rmkhome# dig @127.0.0.1 version.bind text chaos

; <<>> DiG 8.3 <<>> @127.0.0.1 version.bind text chaos 
; (1 server found)
;; res options: init recurs defnam dnsrch

;; MSG SIZE  sent: 22  rcvd: 22

From /var/adm/messages:

rmkhome# grep "8.2.3-REL" /var/adm/messages
Jan 27 20:25:49 rmkhome named[29156]: starting (/etc/named.conf).  named 8.2.3-REL Sat Jan 27 19:42:57 MST 2001

Looks like it refuses to return version queries, by default.
