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.
