AS10474Dimension Data

South AfricaRegistryAFRINICTypeEyeball

As of 10th November 2026, AS10474 (Dimension Data), an access network registered in South Africa with AFRINIC, originates 18 IPv4 prefixes covering 1.4M addresses. By IPv4 address space that makes it the 378th-largest of the 80,723 networks we see originating IPv4, and the 11th-largest of 657 in South Africa. It is seen behind 1 upstream network, most often AS3741 (Dimension Data), and in front of 2 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 94% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS10474 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
