GermanyRegistryRIPE NCC

As of 12th November 2026, AS213423 (Lukas Hagen), a network registered in Germany with RIPE NCC, originates 1 IPv4 prefix covering 256 addresses and 3 IPv6 prefixes. By IPv4 address space that makes it the 59,995th-largest of the 80,772 networks we see originating IPv4, and the 1,780th-largest of 2,333 in Germany. It is seen behind 5 upstream networks, most often AS11967 (Hop179 OU) and AS214915 (Jan Smyrek), and in front of 1 downstream network. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 75% 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 AS213423 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.
