It is administered by .MN Registry, Datacom. The domain name is composed of the consonants in the first syllable of the country name. The .MN registry is operated under the thick registry model. Administrative, Billing, Technical and Registrant contacts are required. The Redemption Grace Period (RGP) is available for .MN domains.
The .mn domain name has been used to represent the U.S. state of Minnesota; an example is the Minnesota Senate () but such use is not official in the state. The .mn domain elsewhere outside Mongolia is used primarily as a domain hack, for example vita.mn (a play on vitamin). Another example is cart.mn (a play on the South Park character Eric Cartman, which redirects to www.southparkstudios.com). It is also used by various micronations.
In 2012 a new top domain was registered for Mongolia, intended for domain names in the local language. This top domain is .мон. Registrations for the domain opened in May 2014. The first site http://мон.мон became active during that month.
