             Root Causes and Mitigation of Name Collisions

Abstract

   This document provides context and a report of a workshop on Root
   Causes and Mitigation of Name Collisions, which took place in London,
   United Kindgdom, on March 8 to 10, 2014. The main goal of the
   workshop was to foster a discussion on the causes and potential
   mitigations of domain name collisions. This report provides a small
   amount of background and context, then provides a summary of the 
   workshop's discussions.

1  Introduction

   It has been well known within the Internet research and engineering
   community that many installed systems in the Internet query the DNS
   root for a wide range of top-level domains (TLDs).  Many of these
   TLDs are not delegated which results in a response indicating that
   the name queried does not exist (commonly called an NXDOMAIN
   response). In the ICANN community, it was observed as early as
   November 2010 by the Security and Stability Advisory Committee (SSAC)
   report [SAC045] that the addition of new top-level domains in the DNS
   root could result in so-called name collisions for installed systems.
    Some installed systems, following established (albeit not vetted)
   operational practices, generate queries to the global DNS with name
   suffixes that under seemingly reasonable assumptions at the time the
   systems were designed or configured, were not expected to be
