As of 11th November 2026, AS265828 (Infomaster S.R.L.), a network registered in Argentina with LACNIC, originates 3 IPv4 prefixes covering 2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 25,847th-largest of the 80,747 networks we see originating IPv4, and the 330th-largest of 1,080 in Argentina. It is seen behind 1 upstream network, most often AS61599 (EAI TELECOMUNICACOES LTDA), and in front of 2 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS265828 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.
