What is ICANN?
The Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit, private organization that was incorporated in California on September 18, 1998. ICANN is tasked with administrative duties associated with running the Internet. These duties were formerly handled by the U.S. government. ICANN's functions include managing top-level domains (TLDs) such as .com, .net, and .org, maintaining the directory of domain names used in the Internet protocol (IP), and resolving trademark disputes over domain names. ICANN also oversees policy regarding Internet domain names and numbers.

Why was ICANN created?
ICANN was created in response to the U.S. Department of Commerce (DOC) goals for managing domain names. It manages the domain name system (DNS), which translates domain names into computer-readable addresses, and also accredits independent registrars that issue domain names. As commercial activity grew on the Internet, ICANN was also tasked with resolving disputes, especially those caused by cybersquatters. In 2016, the United States ended its contract with ICANN, placing management of the DNS completely under ICANNās control.

What does ICANN do for the Internet?
ICANN, a non-profit organization, plays a crucial role in the administration of the Internet. It oversees top-level domains (TLDs) like .com, .net, and .org, manages the registration of domain names used in the Internet protocol (IP), and resolves trademark disputes related to domain names.
ICANN manages the domain name system (DNS), which translates domain names into computer-readable addresses, ensuring the correct flow of information. It accredits independent registrars globally, who issue domain names to individuals and businesses. ICANN also addresses disputes over domain names, particularly those arising from cybersquatting, through its Uniform Domain Name Dispute Resolution Policy.
Furthermore, ICANN has expanded the number of TLDs and introduced internationalized domain names (IDNs) to support various languages. Since 2016, ICANN has managed the DNS completely under its control.

How does ICANN help organize domain names like .com and .org?
ICANN, a nonprofit organization, plays a crucial role in managing the Internet's domain name system (DNS). It oversees top-level domains (TLDs) like .com, .net, and .org, and maintains the directory of domain names used in the Internet protocol (IP). DNS servers translate domain names into computer-readable addresses, ensuring information flows correctly.
ICANN accredits independent registrars globally, who then issue domain names to individuals and businesses. It also enforces policies to resolve domain name disputes, protecting businesses from cybersquatters. ICANN's management of the DNS is critical for the Internet's functionality.

Who makes decisions at ICANN?
ICANN is a nonprofit private organization that handles various administrative duties associated with running the Internet. ICANN's board of directors made decisions such as voting in favor of adding new suffixes and approving the .xxx top-level domain. In 2009, the U.S. government relinquished its sole right to annual reviews of ICANN and took only one seat on ICANNās board, along with representatives of 11 other countries. In 2016, the United States ended its contract, which placed managing the DNS completely under ICANNās control.

How does ICANN influence how people access websites worldwide?
ICANN, a nonprofit organization, plays a crucial role in how users access websites globally by managing the domain name system (DNS). This system translates domain names like www.britannica.com into IP addresses that computers use to locate websites.
ICANN accredits registrars that issue domain names and resolves trademark disputes to ensure fair practices. It also introduces new top-level domains (TLDs) and supports internationalized domain names (IDNs), enabling domain names in various languages, thus broadening Internet accessibility for a global audience.

ICANN, nonprofit private organization incorporated in California on September 18, 1998, and tasked with taking over from the U.S. government various administrative duties associated with running the Internet. ICANNās functions include overseeing the top-level domains (TLDs; e.g., .com, .net, .org, .edu, .us), registering and maintaining the directory of domain names (e.g., www.britannica.com) used in the Internet protocol (IP), and resolving trademark disputes over domain names.
In 1997 U.S. Pres. Bill Clinton signed the Framework for Global Electronic Commerce, directing the Department of Commerce (DOC) to oversee the growth of business over the Internet. Although Clinton emphasized the importance of the private sector in his directive to the DOC, the U.S. government retained ultimate control through the Joint Project Agreement.
The Framework set goals for the management of domain namesāa function for which ICANN was purposely created. Managing the domain name system (DNS) is critical to the functioning of the Internet. DNS servers provide automated lookup or telephone directory-like services, translating domain names into computer-readable addresses so that information will flow to and from the correct places. ICANN issues accreditations to more than 1,000 independent registrars worldwide that issue domain names to individuals, businesses, and other site owners on the Internet. The organization has revoked those credentials when registrars violate the terms of the Registrar Accreditation Agreement, such as it did with Parava Networks in 2009 for, among other violations, failing to accurately maintain information about some Web sites it had registered.
Since the 1990s the exclusive right to use Internet domain names has been a highly contested issue. Domain name labels enable āpacketsā of information transmitted over the Internet to be delivered to their intended destinations, using the transmission control protocol/Internet protocol; the whole system of transmission and addressing is known as TCP/IP. The mnemonic character of domain names assists consumers in locating Internet-based businesses. As commercial activity on the Internet grew, evocative domain names became increasingly valuable, and struggles over them multiplied, especially as a result of the activities of so-called cybersquatters, who registered popular domain names with the aim of ransoming them to businesses at huge profits. On taking over administration of the Internet, ICANN promulgated a Uniform Domain Name Dispute Resolution Policy to resolve domain name controversies. ICANN also licensed several arbitration services to interpret and enforce it, with the assistance of the World Intellectual Property Organization. The first cases under ICANNās dispute resolution policy, including those brought by the World Wrestling Federation and by American actress Julia Roberts, were settled in 2000.
In 2000 ICANNās board of directors, after debating a list of close to 200 new top-level domain names submitted by numerous organizations, voted in favour of adding seven new suffixes: .aero (for aviation sites), .biz (businesses), .coop (cooperatives), .info (general information), .museum (museums), .name (individuals), and .pro (professionals, such as doctors). In 2003 ICANN added .asia (for Asian sites), .cat (Catalan language), .jobs (employment), .mobi (mobile devices), .tel (contact information), and .travel (tourism). With the exception of the .info domain, few sites have registered in the new domains. In 2010, after years of legal controversy, ICANN approved the .xxx top-level domain for adult entertainment sites. ICANN then announced in 2011 that it would greatly increase the number of top-level domains by allowing nearly any new top-level domain name in any language.
As the Internet and World Wide Web became a global force, some critics felt that the United States had too much control over ICANN. Pressure for a more-independent structure persisted until 2009, when the U.S. government signed the Affirmation of Commitments, in which it relinquished its sole right to annual reviews of ICANN and took only one seat on ICANNās board, along with representatives of 11 other countries. However, the United States did maintain ultimate stewardship of the Internet Assigned Numbers Authority (IANA), which coordinates some of the key technical underpinnings of the Internet, such as managing the DNS root. IANA also controls specific TLDs, such as .arpa. ICANN manages IANA under contract with the DOCās National Telecommunications and Information Administration, to which ICANN files quarterly technical reports. In 2016 the United States ended its contract, which placed managing the DNS completely under ICANNās control.
According to ICANN, the native languages of more than half of the Internetās users are not Latin-based. Accordingly, in 2007 ICANN began testing the use of non-Latin script in the software used by DNS servers to locate TLD resources on the Internet. These internationalized domain names (IDNs) initially included Chinese, Arabic, and Cyrillic characters in addition to the long-serving Latin letters A to Z, Arabic numerals 0 to 9, and punctuation symbols such as hyphens. Eventually, IDNs will recognize almost 100,000 characters in many different languages. The first IDNs, which used Arabic characters for domain names in Egypt, Saudi Arabia, and the United Arab Emirates, went into service in May 2010.
