DeCIX

DECIX, commonly written DE-CIX (Deutscher Commercial Internet Exchange), is a German-based Internet exchange point operator. Its flagship exchange is DE-CIX Frankfurt, located in Frankfurt, and the company operates a network of Internet exchanges in cities around the world. The organization provides peering services that enable networks to exchange Internet traffic directly, reducing reliance on upstream transit and improving latency and resilience.

Networks connect through DE-CIX via route servers and private peering arrangements, using carrier-neutral data centers and scalable platforms. The DE-CIX ecosystems support both IPv4 and IPv6, with anycast-based presence across multiple sites to deliver low-latency interconnection globally.

Founded in 1995 in Frankfurt as part of the German Internet exchange landscape, DE-CIX expanded to additional sites across Europe, North America, the Middle East, and Asia, growing its footprint and capacity to accommodate increasing interconnection demand.

DE-CIX is regarded as one of the largest Internet exchange operators by traffic and by the number of connected networks. Its members include Internet service providers, content delivery networks, cloud providers, and enterprises, making it a central component of Internet interconnection in Europe and beyond.
