Root Name Service (DNS)

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.
