BrazilRegistryLACNIC

As of 11th November 2026, AS52863 (UPX TECNOLOGIA LTDA), a network registered in Brazil with LACNIC, originates 8 IPv4 prefixes covering 2k addresses and 12 IPv6 prefixes. By IPv4 address space that makes it the 25,853rd-largest of the 80,743 networks we see originating IPv4, and the 3,583rd-largest of 8,031 in Brazil. It is seen behind 19 upstream networks, most often AS400282 (UPX US LLC) and AS52320 (V.tal (GlobeNet)), and in front of 69 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 85% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS52863 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS52863 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.
