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

  • Discussed revisions to proposed IANA Committee charter, including agreeing to invite Board liaisons to advise the committee, and noting that reviewing current IANA operations is within scope of the committee.
  • Discussed meeting schedule for 2009, starting with teleconferences in January and February, followed by meeting in Mexico.
  • Reviewed content and ranking of initial committee “issues list”:
    1. Root zone management review
    2. Implement new technical checks for TLD name servers to ensure greater DNS security for TLDs
    3. Modify root zone glue record change policy
    4. Transition ARPA operations to ICANN
    5. Transition of IN ‐ ADDR.ARPA operations to ICANN
    6. Protocol parameter process review
    7. Number resource process review
    8. DNSSEC operational readiness
  • Discussed need to refine terminology: RZM software = new software for managing root, vs. root zone management refers to operational processes.
  • Reviewed agenda for next meeting, including review of IANA roles and responsibilities, and review of IANA projects and initiatives.
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"""" is not an IDN."
