As of 11th November 2026, AS265340 (S.M.C Redes e Informatica LTDA), an access network registered in Brazil with LACNIC, originates 5 IPv4 prefixes covering 2.6k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 23,461st-largest of the 80,743 networks we see originating IPv4, and the 3,152nd-largest of 8,031 in Brazil. It is seen behind 2 upstream networks, most often AS262740 (VELOO NET LTDA) and AS266240 (A2 TELECOM EIRELI - ME), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA. 86% 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 AS265340 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.
