Re: Should a nameserver know about itself?

When you send a MaraDNS name server this query: erre-con-erre-cigarro.maradns.org. query txt class 1 (internet) It sends back the version number of the server in question. (The answer that the maradns.org. name servers return is "MaraDNS version number not available") I know that some nameservers send me queries in this form: version.bind. query txt class 3 (what class is class 3 anyway?) Which may be script kiddies looking for older namservers to exploit, or could be dns admins seeing what I run. - Sam
