AS204680KIT Student

GermanyRegistryRIPE NCC

As of 22nd October 2026, AS204680 (KIT Student), a network registered in Germany with RIPE NCC, originates 1 IPv4 prefix covering 256 addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 59,188th-largest of the 79,663 networks we see originating IPv4, and the 1,765th-largest of 2,307 in Germany. It is seen behind 1 upstream network, most often AS553 (BelWü), and in front of 6 downstream networks. 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 AS204680 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.
