fpdns
remotely determine DNS server version
A nameserver basically responds to a query. Interoperability is an obvious requirement here. The standard protocol behaviour of different DNS implementations is expected to be the same. The reality is quite different though. fpdns uses a series of borderline DNS queries to determine the vendor, product and version of a nameserver.
