If my name server queries a European name server for a domain that it is supposed to be authoritative for but isn't, the European server will delegate my server back to the European root servers. It will list the European root name servers in the authority section of the response and their addresses in the additional section. My name server just add these servers to its list of root servers (and pass this information on if it is similarly misconfigured). I have also observered broken name servers responding with the root server list in the authority section just for the heck of it. May I remind everyone that just a few months ago many name servers thought that "GENTER-ADAM.ARPA" was a root server. -- Don "Truck" Lewis Harris Semiconductor Internet: del@mlb.semi.harris.com PO Box 883 MS 62A-028 Phone: (407) 729-5205 Melbourne, FL 32901
