Abstract

   RFC 2916 assigned responsibility for a number of administrative and
   operational details of Telephone Number Mapping (ENUM) to the IAB.
   It also anticipated that ITU would take responsibility for
   determining the legitimacy and appropriateness of applicants for
   delegation of "country code"-level subdomains of the top-level ENUM
   domain.  Recently, three memos have been prepared for the ITU-T Study
   Group 2 (SG2) to explain the background of, and reasoning for, the
   relevant decisions.  The IAB has also supplied a set of procedural
   instructions to the RIPE NCC for implementation of their part of the
   model.  The content of the three memos is provided in this document
   for the information of the IETF community.
