The following is a summary of discussions, actions taken and actions identified:

  • Unanimously approved minutes of the last meeting.
  • Reviewed status of completed work items, including: DNS Technical Checks update was posted to the website; Routing Diversity Report provided; and updated glossary provided to the committee. Action: Staff to update DNS Technical Checks document to include more robust information, as suggested by the IC; Staff to post glossary after Sydney meeting, and to determine process to notify committee where there is a significant update to documents.

  • Discussed status of Root Zone signing discussions and system considerations, and status of design solutions under consideration. VeriSign and NTIA will be presenting to the community during the Sydney meeting, and the entities are working towards architectural solutions and technical requirements specifications. Staff also reported on general signing architecture and status of infrastructure for roots such as dot-ICANN, with testing ready in July. Actions: Staff intends to have draft architecture completed by 1 July 2009 and available for IETF meeting to allow for input, while noting that there are many open issues remaining; Staff to provide IC with draft report on effects of parallel systems.

Domain Name System
Internationalized Domain Name ,IDN,"IDNs are domain names that include characters used in the local representation of languages that are not written with the twenty-six letters of the basic Latin alphabet ""a-z"". An IDN can contain Latin letters with diacritical marks, as required by many European languages, or may consist of characters from non-Latin scripts such as Arabic or Chinese. Many languages also use other types of digits than the European ""0-9"". The basic Latin alphabet together with the European-Arabic digits are, for the purpose of domain names, termed ""ASCII characters"" (ASCII = American Standard Code for Information Interchange). These are also included in the broader range of ""Unicode characters"" that provides the basis for IDNs. The ""hostname rule"" requires that all domain names of the type under consideration here are stored in the DNS using only the ASCII characters listed above, with the one further addition of the hyphen ""-"". The Unicode form of an IDN therefore requires special encoding before it is entered into the DNS. The following terminology is used when distinguishing between these forms: A domain name consists of a series of ""labels"" (separated by ""dots""). The ASCII form of an IDN label is termed an ""A-label"". All operations defined in the DNS protocol use A-labels exclusively. The Unicode form, which a user expects to be displayed, is termed a ""U-label"". The difference may be illustrated with the Hindi word for ""test"" — परीका — appearing here as a U-label would (in the Devanagari script). A special form of ""ASCII compatible encoding"" (abbreviated ACE) is applied to this to produce the corresponding A-label: xn--11b5bs1di. A domain name that only includes ASCII letters, digits, and hyphens is termed an ""LDH label"". Although the definitions of A-labels and LDH-labels overlap, a name consisting exclusively of LDH labels, such as""icann.org"" is not an IDN."
