GermanyRegistryRIPE NCCTypeEyeball

As of 11th November 2026, AS13020 (Chaos Computer Club (Events)), an access network registered in Germany with RIPE NCC, originates 1 IPv4 prefix covering 8.2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 12,070th-largest of the 80,743 networks we see originating IPv4, and the 433rd-largest of 2,331 in Germany. It is seen behind 1 upstream network, most often AS50472 (Chaos Computer Club e.V.). 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 AS13020 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.
