ICANN Signs Memorandum of Understanding with the Global Cyber Alliance

LOS ANGELES – 16 June 2020 – Today, the Internet Corporation for Assigned Names and Numbers (ICANN) announced the signature of a Memorandum of Understanding (MoU) with the Global Cyber Alliance (GCA). The MoU aims to bolster the relationship between ICANN and the GCA and enhance their collaboration in support of an efficient and resilient Domain Name System (DNS). These efforts are of interest to both parties and target important issues, such as security threats to the DNS.

"For ICANN org and GCA to work together on research and increasing awareness of the different forms of DNS abuse is something that makes complete sense. As we join forces, we will leverage each other's strengths to support and protect our unique communities which, in the end, make up one single, global community" – Göran Marby, ICANN President and CEO.

"GCA shares ICANN's vision of secure Internet infrastructure, and we are proud to partner with ICANN to achieve that. We all depend on the DNS, therefore improving the security and privacy DNS provides can extend across the Internet to protect everyone, especially including vulnerable communities." – Philip Reitinger, GCA President and CEO.

Security threats to the DNS affect millions of Internet users and are a primary concern for both organizations. The MoU is intended to advance the organizations' shared objective of supporting activities aimed at reducing abuse of the DNS. ICANN and GCA have agreed to collaborate on activities aimed at reducing risk in the DNS. These activities may include research projects; projects to increase capabilities to address threats to and abuse of the DNS; coordination of efforts to bring stakeholders together; and exchange of information.

About GCA

GCA is an international, cross-sector effort dedicated to eradicating cyber risk and improving our connected world. The GCA was formed in September 2015 by the Manhattan District Attorney's office, the City of London Police, and the Center for Internet Security to unite global communities, implementing solutions to address systemic cyber risk and measuring the efforts of those solutions.


ICANN's mission is to help ensure a stable, secure, and unified global Internet. To reach another person on the Internet, you need to type an address – a name or a number – into your computer or other device. That address must be unique so computers know where to find each other. ICANN helps coordinate and support these unique identifiers across the world. ICANN was formed in 1998 as a not-for-profit public-benefit corporation with a community of participants from all over the world.

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."
