A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Domain Name Server Operations Working Group of the IETF. 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.

Internet-Drafts are also available by anonymous FTP. Login with the username "anonymous" and a password of your e-mail address. After logging in, type "cd internet-drafts" and then "get draft-ietf-dnsop-bad-dns-res-00.txt". A list of Internet-Drafts directories can be found in http://www.ietf.org/shadow.html or ftp://ftp.ietf.org/ietf/1shadow-sites.txt Internet-Drafts can also be obtained by e-mail. Send a message to: mailserv@ietf.org. In the body type: "FILE /internet-drafts/draft-ietf-dnsop-bad-dns-res-00.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.
