NORDUnet is an international collaboration between the Nordic national networks for research and education.

NORDUnet interconnects these networks and connects them to the worldwide network for research and education and to the general purpose Internet. The current physical connections are shown on the connectivity map.

NORDUnet provides its services by a combination of leased lines and Internet services provided by other international operators.

In addition to the basic Internet service NORDUnet operates information services and provides USENET NetNews and Multicast connectivity to the Nordic national networks.

NORDUnet also coordinates the Nordic national networks' CERT (Computer Emergency Response Team) activities.

NORDUnet is the result of the NORDUNET programme (1986 to 1992) financed by the Nordic Council of Ministers.
