As of 23rd October 2026, AS28202 (Master Internet), an access network registered in Brazil with LACNIC, originates 1,091 IPv4 prefixes covering 684k addresses and 15 IPv6 prefixes. By IPv4 address space that makes it the 579th-largest of the 79,666 networks we see originating IPv4, and the 12th-largest of 7,987 in Brazil. It is seen behind 17 upstream networks, most often AS37468 (Angola Cables) and AS52320 (V.tal (GlobeNet)), and in front of 34 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 18% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS28202 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS28202 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.
