Through Generic top-level domain

History

The domain edu was implemented in April 1985 as a generic top-level domain. Six universities were the initial registrants that month. The University of California, Los Angeles was among this group of the first schools to have their domains registered. And while the first ARPAnet message was sent from UCLA to Stanford, Stanford did not have their domain registered until half a year after these first schools, becoming the 18th .edu site.

Until 2001, Network Solutions served as registrar for edu under an arrangement with the United States Department of Commerce. Domain registration was done at no cost to educational institutions. In 2001, the Commerce Department entered into a five-year agreement with Educause making that organization the registrar for domain edu. The agreement with Educause was extended for an additional five-year period in 2006; at that time Educause was authorized to begin charging a yearly administrative fee to registrants.

The domain edu was originally intended for educational institutions anywhere in the world. However, most of the institutions that obtained edu registrations were in the United States, while non-U.S. educational institutions typically used country-level domains. In 1993, a decision attributed to Jon Postel limited new registrations in the edu domain to four-year postsecondary educational institutions. This prevented new edu registrations by community colleges and other institutions offering less than four years of postsecondary schooling.

Enforcement of the restrictions in the 1990s was not entirely effective. The webmaster for the Exploratorium, a San Francisco science museum, recalled in 2006 that the museum obtained its edu domain name at a time in the early 1990s "when there were about 600 websites and only one for a museum." The museum's Internet registrar allowed it to sidestep the then-extant domain-naming rules by using edu despite not being an academic institution and by using a name with more than 12 characters. Some community colleges were reported to have registered edu second-level names after 1993. In 1999 an article in Mother Earth News quoted an authority on distance education as saying, "Anyone who has the necessary $70 can register an edu domain name and use it to archive any type of enterprise on the Internet."

In 2001, the domain was restricted to U.S.-accredited postsecondary educational institutions. Subsequent changes expanded its use beyond four-year institutions, allowing registrations by accredited community colleges as well as by university systems, community college districts, and similar entities.

Between 2004 and 2019, the number of registered names in domain edu remained relatively persistent, with more than 7,000 but fewer than 8,000 names registered at any given time.
