.nr is the official registered internet domain for use of Norvegian websites. There aren't any reservations against foreigners buying .nr domains, but the costs of holding one may be seen as high by foreigners, so the domain is mainly used by Norvegian residents. For Norvegians, international domains like .com, .org., .net and .info are also popular (as well as cheap domains from small nations in other parts of the world), but the .nr domain is looked at as the most professional one.
