The domain that is frequently research based is .Edu.
The domain name .edu is a sponsored top-level domain (sTLD) in the Domain Name System of the Internet.
The .edu domain was implemented in April 1985 as a generic top-level domain. Six universities were the first registrants that month.
The .edu domain was first intended for any educational institutions across the world. Nevertheless, most of the institutions that got .edu registrations were in the United States.
