NORDUnet was the first network outside the US accepted to provide a root DNS server. This root name server was officially recognized on 28th July 1991. The root name servers handle the top of the domain-tree, and provide information to other name servers on how to find information about .com, .net, .org or a national top-level domain name.

Details about the I root server (i.root-servers.org) can be found at http://i.root-servers.org.

NORDUnet CERT performs security incident handling in cooperation with the Nordic national research networks. There is a separate page that provides the details.

ftp.nordu.net offers mirrors of IETFs documents, RFCs and IESGs documents.

NetNews is the bulletin board of the Internet consisting of thousands of newsgroups. NetNews forms a virtual network on top of the Internet and beyond called USENET consisting of a mesh of servers sending the news articles to each other.

Statistics concerning the newsfeeds to and from the member networks can be obtained from http://news-stat.sunet.se/usenet.html. The statistics are collected by SUNET.
