As of 11th November 2026, AS52729 (BrNet Informatica), a network registered in Brazil with LACNIC, originates 5 IPv4 prefixes covering 4.1k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 17,380th-largest of the 80,743 networks we see originating IPv4, and the 1,511th-largest of 8,031 in Brazil. It is seen behind 9 upstream networks, most often AS61568 (ALOO TELECOM - FSF TECNOLOGIA SA) and AS14840 (BR.DIGITAL), and in front of 4 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 AS52729 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.
