Global Domains Division (GDD) Metrics

GDD aims to maintain a culture of excellence in its operations. This web page provides information about gTLD marketplace health, performance metrics for several operations and a summary analysis report on Registry Service Evaluation Policy process (RSEP) requests.

gTLD Marketplace Health Index

The gTLD Marketplace Health Index (Beta) [PDF, 2.09 MB] presents statistics and trends related to generic top-level domains (gTLDs). It is intended to serve as a basis for community discussion and collaboration for further developing ICANN's gTLD marketplace metrics. ICANN is working with a community Advisory Panel to refine the Index in preparation for publishing version 1.0. ICANN intends to publish these statistics twice a year. The gTLD Marketplace Health Index (Beta) was first published in July 2016 and updated in December 2016.

More information about the Advisory Panel's work is available on the community wiki.

Operational Metrics

Performance Metrics

The performance metrics below are calculated on a rolling 12-month basis. The information will be updated monthly and published by the end of the following month.

Summary Analysis Reports

Summary analysis reports are generated each calendar year. The information will be updated annually and published by the end of the first calendar quarter.

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."
