|TITLE:||Re. Administrative issues associated with ENUM|
The IAB has reviewed the concerns of ITU-T SG2 expressed in your liaison statement of 18-28 May 2004.
The IAB is concerned that the liaison statement uses terminology that is foreign to the ENUM Standard (IETF RFC3761), and in some cases uses terms that can be confused from other contexts (e.g., calling e164.arpa a “Top Level Domain”). In the interest of continued clarity, we therefore explicitly reject the terminology and text of that liaison statement, and any roles or relationships that may be inferred from them.
With regards to the substance of the concern regarding operational stability, we would like to remind you that the IAB has committed to coordinating with the ITU-TSB (in its role of designated expert for the ENUM Standard) before making changes to the ENUM registry and the operation of e164.arpa. These commitments are publicly and formally documented in our liaison statements to ITU-T SG2 of September 2002 http://www.iab.org/documents/docs/sg2-liaison-sep-02.html and again in February 2003 http://www.iab.org/documents/docs/sg2-liaisona-feb-03.html as well as the ENUM Standard itself, in Section 5 (“IANA Considerations”) of RFC3761. We would further observe that changing the domain of the ENUM standard, from “e164.arpa” to any other value, would require a standards action within the IETF. The IAB could not make such a change unilaterally, and any such proposal would involve a public and open review process.
We hope this clarifies the situation.
