"There are only 13 root name servers in the world. The world trusts Netnod to operate one."

I-root
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.

DNS
Our DNSNODE service is the leading anycast and unicast slave service for TLDs and partners.
Based on one of the most resilient, robust, and advanced networks in the world, DNSNODE has been developed with the same expertise we use to operate i-root and advise the UN, the EU and the Swedish government on DNS best practise.
