GermanyRegistryRIPE NCC

As of 14th November 2026, AS29515 (Hessische Zentrale fuer…), a network registered in Germany with RIPE NCC, originates 25 IPv4 prefixes covering 26.4k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 6,158th-largest of the 80,840 networks we see originating IPv4, and the 211th-largest of 2,340 in Germany. It is seen behind 2 upstream networks, most often AS28676 (WiTCOM Wiesbadener Informations- und…) and AS12306 (Plus.line AG). None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS29515 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.
