As of 10th November 2026, AS30999 (Emtel), an access network registered in Mauritius with AFRINIC, originates 173 IPv4 prefixes covering 732k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 575th-largest of the 80,723 networks we see originating IPv4, and the 3rd-largest of 30 in Mauritius. It is seen behind 38 upstream networks, most often AS6461 (Zayo Bandwidth) and AS37468 (Angola Cables), and in front of 8 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 96% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS30999 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.
