As of 26th September 2026, AS263665 (TECNET PROVEDOR DE ACESSO AS REDES DE…), an access network registered in Brazil with LACNIC, originates 8 IPv4 prefixes covering 8.2k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 11,864th-largest of the 79,516 networks we see originating IPv4, and the 835th-largest of 7,982 in Brazil. It is seen behind 1 upstream network, most often AS28220 (Alares Internet), and in front of 2 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 91% 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 AS263665 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.
