Summary

  • The IETF’s public liaison record identifies 15 August 2026 as the action date for an ITU-T Member State consultation on possible closure of country-code delegations in e164.arpa.
  • The notice supplies neither a stated cut-off time nor a published decision. A passed date is not evidence that ENUM has been closed, or that any delegation has changed.

e164.arpa is part of the Internet’s .arpa infrastructure domain. IANA describes its purpose narrowly: mapping E.164 telephone numbers to Internet URIs. That makes the consultation an infrastructure-governance question, not merely a discussion of legacy numbering policy.

The IETF Datatracker liaison records the request from ITU-T Study Group 2 to the IAB and IETF General Area. The attached TSB Circular 123 asks Member States whether they agree or do not agree with a possible closure, citing negligible traffic, non-functional delegations and no currently anticipated service as material considered in the consultation.

This briefing reports the notice, not a result. The documents name 15 August 2026 but no clock or time zone; by this report’s publication date, the named date has passed. They do not announce approval, rejection, implementation, a service shutdown or an altered DNS delegation. The IANA .arpa registry remains the public description of the namespace’s function.
