.no is the Internet country code top-level domain (ccTLD) for Norway. Norid, the domain name registry, is based in Trondheim, is owned by the state-owned Uninett and operates under supervision of the Norwegian Communications Authority. As of December 24, 2022 there were 843,749 registered .no domains. Organizations with a presence in Norway and registration at the Brønnøysund Register Centre are limited to 100 domains each. Individuals residing in Norway may register in the second-level domain and, as of June 17, 2014, directly under . Other second-level domains exist for organizations of certain types, such as municipalities and schools. The strict regulations have resulted in near-absence of cybersquatting and warehousing. Management of a ccTLD was awarded to Pål Spilling in 1983, but was taken over by Uninett four years later. The 1000th domain was registered in 1995. Norid is the result of several re-organizations within Uninett, in 2003 becoming a separate limited company. Norway has also been allocated two other ccTLDs, for Svalbard and Jan Mayen and for Bouvet Island; neither are open to registration. Originally only a single domain was permitted per organization, and this was manually checked by Norid to ensure compliance with trademark ownership. The regulations were liberalized in 2001, when the process was automated and a retrospective dispute resolution scheme was introduced. This resulted in a boom of registrations, with the accumulated registrations exceeding 100,000 in the course of the year. Domain names may consist of the twenty-six basic Latin letters, digits and the hyphen, and beginning in 2004 three Norwegian language letters and twenty Sami language letters have been permitted. All-numeric domains were introduced in 2007 and in 2011. History The domain name registry responsibility for was in 1983 awarded to Pål Spilling at the Norwegian Telecommunications Administration's Research Institute. The actual registration work was carried out by Jens Thomassen. The first registered domains were (the Norwegian Telecommunications Administration) and (the Department of Informatics at the University of Oslo). Initially the workload of domain registration was light, but after a few years the workload had become unmanageable as a side project for an individual. Policy-makers also indicated a need for the domain registration to be managed by a non-commercial organization. The responsibility was therefore transferred to the publicly owned Uninett, a supplier of information and communications technology to Norwegian public universities, colleges and research institutions on 17 March 1987.
