A new Request for Comments is now available in online RFC libraries. BCP0123 RFC 4697 Title: Observed DNS Resolution Misbehavior Author: M. Larson, P. Barber Status: Best Current Practice Date: October 2006 Mailbox: mlarson@verisign.com, pbarber@verisign.com Pages: 18 Characters: 45187 Updates: See-Also: BCP0123 I-D Tag: draft-ietf-dnsop-bad-dns-res-06.txt URL: http://www.rfc-editor.org/rfc/rfc4697.txt 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.
