library to determine DNS server vendor, product and version

Identifying individual nameserver implementations is based on "borderline" protocol behaviour. The DNS protocol offers a multitude of message bits, response types, opcodes, classes, query types and label types in a fashion that makes some mutually exclusive while some are not used in a query messages at all.

Not every implementation offers the full set of features the DNS protocol set currently has. Some implementations offer features outside the protocol set, and there are implementations that do not conform to standards.
