Fortunatly, his other suggestion about sending a status opcode will get a "not implemented" response from the "nortorious implementation" in question. The only DNS server I know about that has version out there that don't correctly handle the "status" opcode is my own implentation of a DNS server. It used to handle a status query like a normal query. In fact, Mark's posting made me realize that my implementation had this problem. In light of his posting, I just released a new bugfix release because of this issue. - Sam
