RussiaRegistryRIPE NCC

As of 12th November 2026, AS215457 (DCS LLC), a network registered in Russia with RIPE NCC, originates 6 IPv4 prefixes covering 2.3k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 24,611th-largest of the 80,772 networks we see originating IPv4, and the 1,416th-largest of 4,985 in Russia. It is seen behind 5 upstream networks, most often AS20764 (CJSC RASCOM) and AS196695 (NetOne Rus JSC), and in front of 3 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 AS215457 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.
