In the Internet, a domain name is a string that identifies a realm of administrative autonomy, authority or control. Domain names are often used to identify services provided through the Internet, such as websites, email services and more. As of December 2023, 359.8 million domain names had been registered. Domain names are used in various networking contexts and for application-specific naming and addressing purposes. In general, a domain name identifies a network domain or an Internet Protocol (IP) resource, such as a personal computer used to access the Internet, or a server computer.
.eu is the country code top-level domain (ccTLD) for the European Union (EU). Launched on 7 December 2005, the domain is available for any person, company or organization based in the European Union. This was extended to the European Economic Area in 2014, after the regulation was incorporated into the EEA Agreement, and hence is also available for any person, company or organization based in Iceland, Liechtenstein and Norway. The TLD is administered by EURid, a consortium originally consisting of the national ccTLD registry operators of Belgium, Sweden, and Italy, joined later by the national registry operator of the Czech Republic. Trademark owners were able to submit registrations through a sunrise period, in an effort to prevent cybersquatting. Full registration started on 7 April 2006.
