As of 11th November 2026, AS51852 (Private Layer INC), a content network registered in Panama with RIPE NCC, originates 100 IPv4 prefixes covering 36.9k addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 5,161st-largest of the 80,743 networks we see originating IPv4, and the 8th-largest of 95 in Panama. It is seen behind 1 upstream network, most often AS43440 (Digitale Suisse AG). 29% of its announcements have a valid RPKI ROA; 1 is RPKI-invalid. Over 99% 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 AS51852 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.
