Reviews are one of several important ICANN accountability mechanisms. Organizational Reviews and Specific Reviews (formerly AoC Reviews) provide the means for independent assessment of ICANN’s performance toward its commitments.

Reviews are a progress report that demonstrates how ICANN delivers on its commitments and identifying areas for improvement.  Reviews promote a common goal: a single, interoperable Internet supported by stable, secure and resilient unique identifier systems.  This allows the Internet to be free and open and will help shape the future of the World Wide Web.

Find What you Need: We have provided an overview of the resources available to help you find the review-related information you need.

The Specific Reviews Page and Organizational Reviews Page offer an introduction to each review type, the Reviews process itself, and links to the implementation of Specific and Organizational Reviews Recommendations. On these pages you can find a list of all the Reviews in each category along with links to their landing pages on and the wiki.

Individual home pages for each of the Specific and Organizational reviews provide a permanent file of essential milestones, outputs, and final deliverables for each Review. At the top of each page, you will also find quicklinks to important resources such as the wiki landing page, implementation progress of Review recommendations, and Review fact sheets that share detailed information on the progress of Review Teams and resources used.

Review wiki landing pages provide a great way to follow and get involved with Reviews. They provide up-to-date information on the work of each Review Team in real time including the latest news, updates, and opportunities to participate.

See below for a timeline of past, current, and future specific and organizational Reviews.

Projected Timeline of Upcoming Reviews

The timing of reviews is defined by ICANN Bylaws. Reviews are on a five year cycle.

This Reviews timeline provides a snapshot of the active Specific Reviews (in blue) and Organizational Reviews (in orange). The timeline includes the planning, execution, and implementation activity for each Review. For a more detailed overview of the review process, visit the Process Flow infographics for Specific Reviews or Organizational Reviews.

The Review Cycle Overview provides an expanded timeline to demonstrate the past, current, and future specific reviews (in blue) and organizational reviews (in orange) over an extended timeline of 22 years.

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."
