As of 10th November 2026, AS50518 (G&L Geissendoerfer & Leschinsky GmbH), a network registered in Germany with RIPE NCC, originates 4 IPv4 prefixes covering 1.3k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 34,015th-largest of the 80,723 networks we see originating IPv4, and the 1,075th-largest of 2,329 in Germany. It is seen behind 3 upstream networks, most often AS6939 (Hurricane Electric LLC) and AS2914 (NTT America, Inc.). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 80% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS50518 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.
