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.}, }
