As of 26th September 2026, AS28220 (Alares Internet), an access network registered in Brazil with LACNIC, originates 222 IPv4 prefixes covering 514k addresses and 49 IPv6 prefixes. By IPv4 address space that makes it the 708th-largest of the 79,516 networks we see originating IPv4, and the 17th-largest of 7,982 in Brazil. It is seen behind 27 upstream networks, most often AS52320 (V.tal (GlobeNet)) and AS7195 (EdgeUno), and in front of 63 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS28220 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.
