As of 11th November 2026, AS13101 (TNG Stadtnetz GmbH), an access network registered in Germany with RIPE NCC, originates 33 IPv4 prefixes covering 142k addresses and 4 IPv6 prefixes. By IPv4 address space that makes it the 1,763rd-largest of the 80,747 networks we see originating IPv4, and the 46th-largest of 2,331 in Germany. It is seen behind 44 upstream networks, most often AS3356 (Lumen (Level 3)) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 12 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS13101 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.
