As of 27th September 2026, AS2715 (Fundação Carlos Chagas Filho de Amparo…), a network registered in Brazil with LACNIC, originates 60 IPv4 prefixes covering 355k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 868th-largest of the 79,540 networks we see originating IPv4, and the 21st-largest of 7,985 in Brazil. It is seen behind 4 upstream networks, most often AS1916 (RNP - Rede Nacional de Ensino e Pesquisa) and AS6939 (Hurricane Electric LLC), and in front of 3 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 AS2715 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.
