you can always try:
dig @dns.server.to.query version.bind chaos txt
which would return something like:
;; QUESTION SECTION:
;version.bind. CH TXT
;; ANSWER SECTION:
version.bind. 0 CH TXT "djbdns 1.05"
(sorry for the djbdns .... i found no bind that allows that for
examplifying it :) )
the big problem here is that DNS servers, quite usually, do not
accept this queries or, in some other quite usual configuration, change
the text for some generic string, which can be easily done in BINDs for
example:
;; ANSWER SECTION:
version.bind. 0 CH TXT "version goes here"
there's absolutely no guaranteed way of getting the correct version
running on DNSs server you have no admin access. The only guaranteed to
work 100% of the simes still seems to be the 'named -v' on the machine's
console.
