NIX.CZ, z.s.p.o. (Professional Association of Legal Entities) is a company, which associates Czech, and foreign Internet related businesses in order to mutually interconnect their networks. Access to the company’s infrastructure is enabled through five collocations in Prague. Currently, the NIX.CZ association is the largest Neutral IXP (Internet Exchange Point) in the Czech Republic and ranks among the 10 largest IXPs in Europe. Consistent and meticulous planning, sophisticated technical solutions and a 24/7/365 technical support have led to a failure-free operation of the node. The association has encouraged and facilitated IPv6 protocol- based peering since 2003. NIX.CZ is a dynamic company, which actively participates in the development of the Internet. Through their General Meetings and Social Events we enable their members and customers to meet, not as competitors but as allies, cooperating on the future of the association. The NIX.CZ association also organises free lectures on current topics for its members.
