South AfricaRegistryAFRINIC

As of 26th September 2026, AS37315 (Cipherwave), a network registered in South Africa with AFRINIC, originates 48 IPv4 prefixes covering 88.1k addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 2,589th-largest of the 79,516 networks we see originating IPv4, and the 34th-largest of 653 in South Africa. It is seen behind 4 upstream networks, most often AS37662 (West Indian Ocean Cable Company (WIOCC)) and AS30844 (Liquid Intelligent Technologies), and in front of 8 downstream networks. None of its announcements have a valid RPKI ROA. 96% 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 AS37315 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.
