INX-ZA, a division of ISPA, operates community-run Internet exchange points in Johannesburg (JINX), Cape Town (CINX) and Durban (DINX). Building on the original JINX founded by ISPA, INX-ZA now operates multisite exchanges in each city. These exchanges provide a neutral facility for ISPs and operators of IP networks to connect and exchange traffic in South Africa and encourage the routing of domestic Internet traffic by providing an optimal path for traffic to reach other networks within the same city, country or continent.
