Title : Observed DNS Resolution Misbehavior
Author(s) : P. Barber, J. Brady, M. Larson
Filename : draft-ietf-dnsop-bad-dns-res-00.txt
Pages : 14
Date : 13-Nov-01
This Internet-Draft describes DNS name server and stub resolver
behavior that results in a significant query volume sent to the
root and top-level domain (TLD) name servers. In some cases we
recommend minor additions to the DNS protocol specification and
corresponding changes in name server implementations to alleviate
these unnecessary queries. In one case, we have highlighted
behavior of a popular name server implementation that does not
conform to the DNS specification. 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/org 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.
