Abstract

   The Special-Use Domain Names registration policy in RFC 6761 has been
   shown through experience to present unanticipated challenges.  This
   memo explores current IETF and non-IETF publications relating on
   special-use TLDs, describes the history of domain names, and
   enumerates some problems that have come up in connection with the
   Special-Use Domain Names allocation process specifically as it
   related to top-level domains.

1.  Introduction

   At the time of this writing, the IETF has recently been asked to
   allocate several new special-use top-level domains (SUTLDs), and has
   experienced several different sorts of problems with the process as
   documented in Special-Use Domain Names [RFC6761].  Because of this,
   the IETF has decided to investigate the problem and decide if and how
   the RFC 6761 process can be improved, or whether it should be
   deprecated.

   In order to investigate this question, this document attempts first
