	Title		: Observed DNS Resolution Misbehavior

This memo describes DNS iterative resolver behavior that results in a
significant query volume sent to the root and top-level domain (TLD)
name servers.  We offer implementation advice to iterative resolver
developers to alleviate these unnecessary queries.  The
recommendations made in this document are a direct byproduct of
observation and analysis of abnormal query traffic patterns seen at
two of the thirteen root name servers and all thirteen com/net TLD
name servers.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
