About this network

Internet Solutions (IS) — a long-established South African business ISP and transit provider, part of the Dimension Data / NTT group.

What it's used for

• Enterprise internet access, connectivity, and transit across South Africa and the region.

Notable

• Not a mobile carrier: this is a business-focused ISP and backbone network, so addresses here are corporate connections and hosted services rather than consumer mobile devices.
• One of the older and larger commercial networks in South Africa, now folded into the NTT DATA global organisation.

Interesting

• Internet Solutions was among the pioneers of commercial internet in South Africa before being absorbed into Dimension Data and later NTT.
