As of 25th October 2026, AS265023 (TMK NET LTDA), an access network registered in Brazil with LACNIC, originates 7 IPv4 prefixes covering 7.4k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 12,857th-largest of the 79,675 networks we see originating IPv4, and the 973rd-largest of 7,990 in Brazil. It is seen behind 2 upstream networks, most often AS267613 (ELETRONET S.A.) and AS61832 (Giga+ Empresas), and in front of 28 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS265023 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.
