GermanyRegistryRIPE NCC

As of 22nd October 2026, AS47610 (RWTH Aachen University), a network registered in Germany with RIPE NCC, originates 12 IPv4 prefixes covering 265k addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 1,072nd-largest of the 79,663 networks we see originating IPv4, and the 28th-largest of 2,307 in Germany. It is seen behind 1 upstream network, most often AS680 (Deutsches Forschungsnetz (DFN)). 94% of its announcements have 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 AS47610 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.
