As of 11th November 2026, AS50923 (Metroset Ltd.), an access network registered in Russia with RIPE NCC, originates 16 IPv4 prefixes covering 39.2k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 5,019th-largest of the 80,743 networks we see originating IPv4, and the 200th-largest of 4,983 in Russia. It is seen behind 22 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS28917 (Fiord Networks, UAB), and in front of 6 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 41% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS50923 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS50923 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.
