As of 24th October 2026, AS272747 (Supernet), an access network registered in Brazil with LACNIC, originates 1 IPv4 prefix covering 256 addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 59,182nd-largest of the 79,664 networks we see originating IPv4, and the 7,438th-largest of 7,989 in Brazil. It is seen behind 4 upstream networks, most often AS265933 (connectx serviços de telecomunicações…) and AS264329 (ESTRATEGIA REDES DE TELECOMUNICACOES…), and in front of 1 downstream network. None of its announcements have a valid RPKI ROA. 60% 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 AS272747 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.
