RussiaRegistryRIPE NCCTypeCarrier

As of 26th September 2026, AS20764 (CJSC RASCOM), a transit carrier registered in Russia with RIPE NCC, originates 5 IPv4 prefixes covering 13.6k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 8,909th-largest of the 79,480 networks we see originating IPv4, and the 467th-largest of 4,941 in Russia. It is seen behind 57 upstream networks, most often AS3491 (PCCW Global (HK) Ltd.) and AS3356 (Lumen (Level 3)), and in front of 262 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 86% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS20764 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS20764 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.
