MSK-IX (Moscow Internet eXchange) is an Internet eXchange Point (IXP) with headquarters in Moscow, Russia. With over 500 connected networks and 2,8Tbps of peak traffic (October 2017), MSK-IX is one of the world's largest IXPs. MSK-IX operates Internet eXchanges (IXes) in 9 cities: Moscow, St.Petersburg, Rostov-on-Don, Stavropol, Samara, Kazan, Ekaterinburg, Novosibirsk, Vladivostok and maintains an access PoP in Riga (Latvia). MSK-IX operates a distributed DNS platform, which provides authoritative name servers for the country-code top-level domains (ccTLDs) .RU and .РФ for Russia.
MSK-IX was founded in 1995 pursuant to the treaty signed by 6 Russian ISPs willing to reduce IP-traffic latency and international backhaul costs. The treaty assigned the Russian Institute for Public Networks (RIPN) as the administrator of the forthcoming IP-traffic exchange and defined technical requirements for connecting ISPs. The first MSK-IX PoP was established by RIPN at M9 facility on Butlerova st., 7. In 2001, MSK-IX became an autonomous organization. In 2002, MSK-IX joined Euro-IX, an international association of IXPs.
