Operational statement for i.root-servers.net

The Domain Name System (DNS) is the distributed hierarchical database on which most Internet services and applications rely and depend. The root of this hierarchy is anchored on 13 domain name servers scattered across the globe.

i.root-servers.net is operated by Netnod AB. The i-root service was initially provided by NORDUnet A/S as of July 1991 under the name nic.nordu.net. nic.nordu.net was re-named to i.root-servers.net in 1995 in cooperation with all root server operators. Netnod took over the operations of i.root-servers.net in 2000 through its then subisidiary Autonomica AB.

Funded by our owners and customers, we provide this service for the benefit of the Internet as a whole. Netnod, based in Stockholm, Sweden, operates Internet infrastructure services in the Nordic region, such as Internet exchange points, precision time and frequency services, and DNS services at all levels of the DNS infrastructure. Netnod is a neutral and independent organisation operating in close cooperation with the Internet community.
