Since 2000, Netnod has operated i.root-servers.net, one of the 13 logical Internet DNS root name servers. The I-root service is provided by a set of distributed nodes using IPv4 and IPv6 anycast. There are currently more than 70 nodes distributed across the world.

Hosting an I-root Node

To further improve robustness and availability of this service, Netnod is continuously expanding the I-root anycast network. If you are interested in hosting an I-root node, you can find more information here.

Netnod and the DNS Root Server System  

I-root was the first DNS root server to be established outside the USA and was originally deployed by NORDUnet A/S in July 1991. It has changed configurations a number of times during the years from its humble beginnings as a Sun 4/65 with 40MB RAM. Today i.root-servers.net will respond to an average of several hundred million DNS queries a day from all over the Internet.

Joint root server statement to ICANN

In 2009, Netnod / Autonomica issued a joint statement to ICANN together with other root server operator. This letter can be found here.

The response from Paul Twomey, CEO of ICANN at the time, confirming the mutual commitment of coordinating respective activities related to the operations of the root servers, can be found here
