As of 27th September 2026, AS22381 (SAMM (Megatelecom)), a network registered in Brazil with LACNIC, originates 110 IPv4 prefixes covering 69.6k addresses and 28 IPv6 prefixes. By IPv4 address space that makes it the 3,122nd-largest of the 79,525 networks we see originating IPv4, and the 89th-largest of 7,983 in Brazil. It is seen behind 18 upstream networks, most often AS37468 (Angola Cables) and AS6762 (Telecom Italia Sparkle (Seabone)), and in front of 167 downstream networks. None of its announcements have a valid RPKI ROA. 94% of its routes reach at least 90% of full-feed peers, and 45 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS22381 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.
