ICANN Open Data Initiative

The goal of the Open Data Initiative is to provide public access to a range of data that ICANN generates and collects. The initiative promotes transparency and access to the publicly available data that is relevant to ICANN’s mission.

The data is available as CSV files, a universally supported file format that does not require the use of an API. More datasets will be added as they become available.

Background

ICANN launched the Open Data Platform in 2020 at the request of the community. However, the platform originally used a separately hosted website and required users to log in to access the data.

In 2026, ICANN opted to migrate the available data to a dedicated page on the ICANN website. As a result, anyone is able to view and download the documents or datasets without needing to log in.

This updated approach to providing data access also will reduce the ICANN organization’s maintenance, data storage, and data backup needs, allowing resources to be directed elsewhere.

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."
