Technical Summary

 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, and offers 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.
