AS48031Ivanov Vitaliy Sergeevich
As of 27th September 2026, AS48031 (Ivanov Vitaliy Sergeevich), a content network registered in Ukraine with RIPE NCC, originates 554 IPv4 prefixes covering 142k addresses and 5 IPv6 prefixes. By IPv4 address space that makes it the 1,723rd-largest of the 79,516 networks we see originating IPv4, and the 12th-largest of 1,521 in Ukraine. It is seen behind 4 upstream networks, most often AS9002 (RETN Limited) and AS5405 (Inter.link GmbH), and in front of 1 downstream network. Over 99% of its announcements have a valid RPKI ROA, and none are RPKI-invalid. Over 99% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph
The networks AS48031 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS48031 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.
