NigerRegistryAFRINIC

As of 23rd October 2026, AS37531 (Airtel Niger), a network registered in Niger with AFRINIC, originates 33 IPv4 prefixes covering 10.8k addresses. By IPv4 address space that makes it the 10,076th-largest of the 79,659 networks we see originating IPv4, and the 3rd-largest of 7 in Niger. It is seen behind 2 upstream networks, most often AS327708 (Airtel Rwanda Ltd) and AS16637 (MTN SA (Bayobab)), and in front of 3 downstream networks. None of its announcements have a valid RPKI ROA. 94% of its routes reach at least 90% of full-feed peers, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS37531 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.
