DNS root nameserver i.root-servers.net

Netnod and Autonomica are proud to operate one of 13 root DNS servers as a public service to the Internet.

i.root-servers.net was the first root DNS server outside USA when it was brought into service (now there are root DNS servers operating from Amsterdam and Tokyo as well). It has changed configurations a number of times during the years from its humble beginnings as a Sun 3/60 with 4MB RAM.

To improved the robustness and availability of this service, Netnod and Autonomica are actively deploying copies (known as "instances") of i.root-servers.net in locations all over the world. Therefore "I" is no longer available only from the (main) site in Stockholm, Sweden, but also from several other sites, including:

- NETNOD-IX Stockholm, Sweden
- NETNOD-IX Lulea, Sweden
- FICIX Helsinki, Finland
- LINX London, Great Britain
- PAIX PaloAlto, USA
- MIX Milano, Italy
- CERN/CIXP Geneva, Switzerland
- NIX Oslo, Norway
- WIDE Tokyo, Japan
- MCI Amstedam, Holland
- HKIXP Honkong, China
- CAT Bangkok, Thailand
- QWEST Washington, USA
- DECIX Frankfurt, Germany
- BENIX Bryssels, Belgium
- RONIX Bukarest, Rumenia
- ULAKBIM Ankara, Turkey
- Starlight Chigago, USA
- Jakarta, Indonesia
- Kuala Lumpor, Malysia
- Bejing, Kina
- Mumbai, India
- Kathmandu, Nepal


We expect a number of new sites to be added to this list shortly as a consequence of our collaboration with several other parties on deployment of this infrastructure.

We pay for all the hardware needed to deploy new sites and maintain complete administrative control over each site, but we are happy to accept help with everything else (i.e. rackspace, connectivity, IP transit, etc). Such help is actually crucial to make this expansion possible.

The query load for the root nameservice varies over time and also differs between sites, but on a typical day I will respond to several hundred million DNS queries from all over the Internet.

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