GermanyRegistryRIPE NCC

As of 22nd October 2026, AS199578 (Rheinland-Pfaelzische Technische…), a network registered in Germany with RIPE NCC, originates 4 IPv4 prefixes covering 66.8k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 3,335th-largest of the 79,663 networks we see originating IPv4, and the 104th-largest of 2,307 in Germany. It is seen behind 2 upstream networks, most often AS680 (Deutsches Forschungsnetz (DFN)) and AS2857 (Johannes Gutenberg-Universitaet Mainz), and in front of 1 downstream network. 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 AS199578 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.
