As of 11th November 2026, AS28220 (Alares Internet), an access network registered in Brazil with LACNIC, originates 252 IPv4 prefixes covering 576k addresses and 62 IPv6 prefixes. By IPv4 address space that makes it the 659th-largest of the 80,743 networks we see originating IPv4, and the 15th-largest of 8,031 in Brazil. It is seen behind 22 upstream networks, most often AS7195 (EdgeUno) and AS52320 (V.tal (GlobeNet)), and in front of 66 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, 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.
