As of 27th September 2026, AS37421 (Cellulant LTD), a network registered in Kenya with AFRINIC, originates 6 IPv4 prefixes covering 5.4k addresses. By IPv4 address space that makes it the 15,035th-largest of the 79,523 networks we see originating IPv4, and the 23rd-largest of 220 in Kenya. It is seen behind 3 upstream networks, most often AS37100 (SEACOM Limited) and AS30844 (Liquid Intelligent Technologies), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA. 100% 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 AS37421 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.
