Netnod manages i.root-servers.net, one of the 13 logical Internet DNS root name servers.
i.root-servers.net was the first DNS root server to be established outside the USA. (Today there are also DNS root servers operating from Amsterdam and Tokyo.) It has changed configurations a number of times during the years from its humble beginnings as a Sun 3/60 with 4MB RAM.
To further improve robustness and availability of this service, Netnod is continuously deploying instances of i.root-servers.net in locations all over the world. Therefore "I" is since long now, not only available from the site in Stockholm, Sweden, but also 54 locations around the world.
Today, Netnod manages a robust constellation of servers around the globe, and is committed to further expand the i.root-servers-net server footprint in coming years. While we maintain complete administrative control over each site, we are happy to accept offers of hosting a site in a new location.
The query load for the root name service varies over time and also differs between sites, but on a typical day i.root-servers.net will respond to several hundred million DNS queries from all over the Internet.
