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' IPv6 activities including the 6NET project and the national networks' CERT (Computer Emergency Response Team) activities.
