SIX.SI provides a local exchange of IPv4 and IPv6 traffic between Internet Service Providers (ISPs), Content Providers (CPs) and Hosting Providers (HPs). SIX.SI therefore enables faster and more streamlined traffic exchange between members and can significantly reduce the distance that data must travel from the content provider to the user.
SIX.SI was launched by ARNES in Ljubljana in February 1994, in order to meet the needs of traffic exchange between the ARNES network and commercial internet providers. SIX.SI was one of the first IXPs of its kind in Europe, and the operation and development of the service has been an ongoing activity of ARNES since then.
