INX-ZA is an autonomous division of the Internet Service Providers’ Association (ISPA) of South Africa. We currently operate the only completely community-run Internet exchange points in South Africa, namely the Johannesburg Internet exchange (JINX), Cape Town Internet Exchange (CINX) and Durban Internet Exchange (DINX).

The Internet exchanges (INXes) provide a neutral facility for ISPs and operators of Internet Protocol (IP) networks to connect and exchange traffic. The exchanges encourage the local routing of Internet traffic by providing an optimal path for traffic to reach other networks within the same city, country or continent. This reduces the usage of expensive long-distance links and improves network performance.

Connecting to any of the INXes is easy, and open to any network that has its own IP address space and an autonomous system number.
