As of 26th September 2026, AS216078 (Liam Kremer), a network registered in Germany with RIPE NCC, originates 4 IPv4 prefixes covering 1k addresses and 27 IPv6 prefixes. By IPv4 address space that makes it the 35,810th-largest of the 79,516 networks we see originating IPv4, and the 1,142nd-largest of 2,288 in Germany. It is seen behind 11 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS174 (Cogent Communications, LLC), and in front of 14 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, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS216078 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.
