As of 27th September 2026, AS52840 (UFINET BRASIL S.A.), a network registered in Brazil with LACNIC, originates 8 IPv4 prefixes covering 4.9k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 15,837th-largest of the 79,525 networks we see originating IPv4, and the 1,360th-largest of 7,983 in Brazil. It is seen behind 14 upstream networks, most often AS13786 (Seaborn (Seabras USA, LLC)) and AS52468 (UFINET PANAMA S.A.), and in front of 37 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 89% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS52840 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS52840 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.
