As of 23rd October 2026, AS29423 (gridscale GmbH), a network registered in Germany with RIPE NCC, originates 11 IPv4 prefixes covering 6.7k addresses and 8 IPv6 prefixes. By IPv4 address space that makes it the 13,443rd-largest of the 79,652 networks we see originating IPv4, and the 491st-largest of 2,307 in Germany. It is seen behind 2 upstream networks, most often AS47147 (Anexia Cloud Solutions GmbH) and AS48200 (Opteamax GmbH). 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 AS29423 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.
