Netnod
Netnod Internet Exchange i Sverige is a non-profit, neutral and independent Internet infrastructure organisation based in Sweden. Netnod is owned by the foundation TU-stiftelsen (Stiftelsen för Telematikens utveckling).
Netnod operates six Internet exchange points (IXPs) in five different cities where Internet operators can connect and exchange traffic (peer). The Netnod IX has among the highest amount of traffic per peer in Europe and is fully IPv6 enabled. At the Netnod IXPs, Netnod provides a variety of value adding services such as the RIPE Internet Routing Registry (IRR), Bredbandskollen (a consumer broadband speed test), slave services for several DNS TLDs, the DNS root server i.root-servers.net, as well as distribution of official Swedish time through NTP. These services are provided as part of Netnod's AS number AS8674.Netnod also manages a variety of DNS services. Netnod provides anycast and unicast slave service to TLDs worldwide through its highly respected DNSNODE product. Netnod is also the proud operator of i.root-servers.net, one of the 13 logical DNS root name servers in the world. This service is provided as a public service to the Internet community at-large, as part of Netnods goal to work for the Good of the Internet. Some of the services above were previously offered through “Autonomica”, which was a fully owned subsidiary of Netnod. However in 2010, Autonomica merged with Netnod, leaving the company with the single name Netnod.
== History ==
The predecessor to the TU Foundation / Netnod was the D-GIX, an Internet exchange point that was established at the Royal Institute of Technology (KTH) in Stockholm and operated by KTHNOC. D-GIX had been one of the first IXes that were established in Europe, and quite successful at that. In 1996 a report by a committee, (スウェーデン語:Internetutredningen)) had listed infrastructure that was critical for the operation of the Internet in Sweden. Among the critical infrastructure listed was a robust and reliable Internet exchange. A number of factors led KTH as well as the Swedish ISPs to conclude that a separate legal entity would be a better operational format. After legal consultations, and seeing that the Swedish government seemed keen to play a role in the infrastructure operation, the Swedish ISPs decided to found the TU Foundation. The initial capital came from a government set up foundation, the Knowledge Foundation, KK-stiftelsen, one of the largest Swedish research foundations. The idea behind the ownership model with the foundation was that it would guarantee independence from the operators as well as from the government. Linkage to the operational community comes from the fact that the Swedish university network SUNET appoints one of the board members, and the Swedish Operator Forum appoints two of the Netnod board members.
The TU-Foundation established the operational company Netnod to run the IX. In the beginning Netnod had no staff of its own and all operations were outsourced to the Swedish military. In 2001, Netnod created fully owned a subsidiary called Autonomica. Autonomica was to run the operations for Netnod (who then as well as now, do not have any staff of its own) as well as run the i.root-servers.net on behalf of NORDUnet and do Internet related research. In the beginning the staff mainly focused on DNS and management and the operations continued to be outsourced to the military. However, finally in 2002 Autonomicas staff grew considerably and the contract with the military was ended. Operations is today done entirely by Netnod staff.
