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 55 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 would like to host an I-root node, please contact: info[at]netnod[dot]se

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 3/60 with 4MB 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

    For more information on the DNS root system, see:

    BCP 40 (RFC2870) - Operational guidelines for Root Name Servers.

    Root server maps

    A map of all i.root-servers.net sites around the world can be found on the Netnod home page.  (Map will be up on Netnod's new homepage soon again)

    On www.root-servers.org you will find a list of all the root server operators and all the root server instances around the world.

    What are root name servers?

    Netnod's Lars-Johan Liman answers frequently asked questions about Internet's root servers functions. Read here to better understand how they function.

    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.

    Netnod re-affirms its commitment to the Internet community, to operate i.root-servers.net in a stable manner, independent of any future changes to the IANA stewardship.
