  1. Reviewed the minutes from the prior IC meeting, and all voting members in attendance unanimously approved the minutes.
  2. Received update from staff of progress on action items identified at the previous meeting, with some items carried over.
    • Actions:
      • Staff to finalize posting of external review of root zone management process in line with communication plan.
      • IC to discuss formation of broader communication plan to increase confidence in IANA Functions Department activities.
      • Staff to provide IC with contextual information on the root glue policy, along with a proposal of possible steps forward, in preparation of public posting of the external review and proposals.
      • Once IC reviews staff’s summary of external review of root glue policy by email, staff to publicly post materials.
      • Staff to provide IC with documentation of business assumptions included within the failover and business continuity exercise.
  3. Received an operational status report from Staff on the roll out of DNSSEC and the status of work on signing the ICANN-related zones.
    • Actions:
      • Staff to provide a written status report to the IC on all facets of this work.
  4. Received an update from staff on the IANA Business Excellence program and efforts for improvement, including definition of departmental strategy, completion of documentation, and gathering of metrics to better demonstrate performance.
    • Actions:
      • Staff to work towards external audit of department in FY11.
      • Staff to provide webinar updates to the community on the Business Excellence program.
  5. Received staff update on reviews of functional areas, including: (i) IPv4 address depletion and allocation, including a review of allocation processes in line with the RIR practice and global policy and a discussion of the changes to the various business models due to the depletion of IPv4 addresses/rollout of IPv6; (ii) IPv6 allocation process, based on a global policy, with a report that the processes are moving along; and (iii) ASN allocation, done according to a process, and a modified policy to unify the 16-bit number space with the 32-bit number space is expected to reach the Board soon. The IC discussed that the issues around the ASN allocation are closely scoped with understood risks, and can be managed in the event that the issues are not solved prior to the depletion of the 16-bit pool. The IC also discussed the work being done to add security to routing and allocation, and the discussion surrounding the implementation of RPKI.
    • Actions:
      • Staff to review and propose solutions regarding any change to the practices in IPv4 address allocation currently followed among the RIRs and ICANN.
      • Staff to provide plan for dealing with responding to changing business models of RIRs.
      • Staff to provide IC with report on RPKI at future meeting.
  6. Received update from staff on the IANA functions change process and the work to develop specifics to document this process, including potential inputs form the Business Excellence work.
    • Action:
      • Staff to provide IC with a proposal on further discussion on process changes.
  7. Opened discussion how to coordinate preparations for the anticipated delegation of large numbers of TLDs. Staff confirmed that IANA Functions Department staff has been involved in planning for new gTLDs as it relates to resource consumption within the department, and confirmed that departmental process documentation work is partially geared towards these preparations.
    • Action
      • IC to discuss at future meeting how to assure that coordination is achieved to prepare for the anticipated increase in delegations.
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."
