NORDUnet A/S operates a Nordic IP backbone network that interconnects research and education networks in the Nordic countries to the rest of the world.

NORDUnet currently operates a dual stack IPv4 and IPv6 production network. IPv6 development activities take place in a dedicated network running on top of NorthernLight infrastructure.

NORDUnet connectivity map shows the main connections and their capacities. There is also a printable version of the map, CMYK, 300dpi.

The NORDUnet backbone supports the use of DiffServ and will not touch codepoints used by DiffServ. However, no active measures are taken to support DiffServ-based QoS implementations such as Premium IP. The NORDUnet backbone does not grant traffic priority, but it does allow the transport of for example Premium IP traffic between peering partners.
