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.  This document specifies an Internet Best Current Practices for the
Internet Community, and requests discussion and suggestions for
improvements.

This document is a product of the Domain Name System Operations
