GermanyRegistryRIPE NCC

As of 28th September 2026, AS50801 (David Froehlich), a network registered in Germany with RIPE NCC, originates 3 IPv4 prefixes covering 768 addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 44,919th-largest of the 79,544 networks we see originating IPv4, and the 1,441st-largest of 2,288 in Germany. It is seen behind 1 upstream network, most often AS39083 (David Froehlich). 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 AS50801 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.
