.is (dot is) is the top-level domain for Iceland. The country code is derived from the first two letters of Ísland, which is the Icelandic word for Iceland. Registration of .is domains is open to all persons and companies without any special restriction.
The very first .is domain, hi.is, is the domain of University of Iceland. It was registered on December 11, 1986, making it one of the earliest ever domain registrations.
