AS9123JSC "TIMEWEB"

RussiaRegistryRIPE NCC

As of 10th November 2026, AS9123 (JSC "TIMEWEB"), a network registered in Russia with RIPE NCC, originates 946 IPv4 prefixes covering 242k addresses and 36 IPv6 prefixes. By IPv4 address space that makes it the 1,173rd-largest of the 80,723 networks we see originating IPv4, and the 34th-largest of 4,983 in Russia. It is seen behind 35 upstream networks, most often AS9002 (RETN Limited) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 12 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 97% of its routes reach at least 90% of full-feed peers, and 5 prefixes are also originated by another network.

Upstream graph

The networks AS9123 is seen behind, one and two hops out, drawn from real AS paths.

AS9123Toward the internet core

Networks observed one and two hops upstream of AS9123 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.
