Subject: Status of ITU work on e164.arpa
Dear Colleagues,
The ENUM working group defined [RFC
3761] a specific Internet
Infrastructure domain (e164.arpa) by which an PSTN
number, as
defined in ITU-T Recommendation E.164, can be expressed as
a
Fully Qualified Domain Name (FQDN).
The history and context of
operational decisions undertaken by the
Internet Architecture Board on ENUM
are well documented in
RFC 3245[1].
Several National Regulatory
Authorities have approved the use of the
e164.arpa domain for various trial
and now commercial purposes
in accordance with procedures arrived at between
the IAB and ITU (see
[2] and the revised procedures described in
[3])
In order to facilitate ongoing cooperation in this work, the IAB
would
appreciate an update on the status of the ITU work on e164.arpa,
its
associated Recommendation (draft) E.A-ENUM and its planned
finalization
of the ENUM Recommendation such that the temporary nature of
the
commercial delegations can be resolved. We would sincerely hope that
a
permanent determination from the ITU on e164.arpa as the ENUM domain
be
completed as soon as possible.
For the IAB,
Olaf
Kolkman, Chair
