It has been well known within the Internet research and engineering community that many installed systems in the Internet query the domain name system (DNS) root for names under 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 [RFC7719]). In the Internet Corporation for Assigned Names and Numbers (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 TLDs in the DNS root could result in so-called name collisions for names used in environments other than the global Internet. 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 delegated as TLDs. Many of these installed systems depend explicitly

                  Report from the Workshop and Prize on              Root Causes and Mitigation of Name Collisions


   This document provides context and a report on the workshop on "Root    Causes and Mitigation of Name Collisions", which took place in    London, United Kingdom, from 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, it provides a summary of the    workshop's discussions.
