BrazilRegistryLACNIC

As of 27th September 2026, AS263102 (Flashnet), a network registered in Brazil with LACNIC, originates 5 IPv4 prefixes covering 2k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 25,307th-largest of the 79,523 networks we see originating IPv4, and the 3,429th-largest of 7,982 in Brazil. It is seen behind 2 upstream networks, most often AS52554 (Rede MegasNet Telecomunicações) and AS53180 (INFORTEL COMUNICACOES LTDA), and in front of 2 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS263102 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.
