This draft is a work item of the Domain Name System Operations Working Group of the IETF.
Title : Observed DNS Resolution Misbehavior
Author(s) : M. Larson, P. Barber
Filename : draft-ietf-dnsop-bad-dns-res-01.txt
Pages : 14
Date : 2003-6-25
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 TLD
name servers.

In the body type:
"FILE /internet-drafts/draft-ietf-dnsop-bad-dns-res-01.txt".
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.
