As of 27th September 2026, AS263966 (WorldWifi), an access network registered in Brazil with LACNIC, originates 29 IPv4 prefixes covering 12.8k addresses and 31 IPv6 prefixes. By IPv4 address space that makes it the 9,198th-largest of the 79,540 networks we see originating IPv4, and the 555th-largest of 7,985 in Brazil. It is seen behind 14 upstream networks, most often AS3356 (Lumen (Level 3)) and AS53062 (ACESSOLINE TELECOMUNICACOES LTDA), and in front of 67 downstream networks. None of its announcements have a valid RPKI ROA. 68% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph

The networks AS263966 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS263966 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.
