5. IANA Considerations

   RFC 2916(-> 3761prop) (which this document replaces) requested IANA to delegate
   the E164.ARPA domain following instructions to be provided by the
   IAB.  The domain was delegated according to those instructions.
   Names within this zone are to be delegated to parties according to
   the ITU-T Recommendation E.164.  The names allocated should be
   hierarchic in accordance with ITU-T Recommendation E.164, and the
   codes should be assigned in accordance with that Recommendation.

   IAB is to coordinate with ITU-T TSB if the technical contact for the
   domain e164.arpa is to change, as ITU-T TSB has an operational
   working relationship with this technical contact which needs to be
   reestablished.

   Delegations in the zone e164.arpa (not delegations in delegated
   domains of e164.arpa) should be done after Expert Review, and the
   IESG will appoint a designated expert.

   IANA has created a registry for Enumservices as specified in Section
   3.  Whenever a new Enumservice is registered by the RFC process in
   the IETF, IANA is at the time of publication of the RFC to register
   the Enumservice and add a pointer to the RFC itself.
