BulgariaRegistryRIPE NCCTypeEyeball

As of 26th September 2026, AS8866 (Vivacom Bulgaria EAD), an access network registered in Bulgaria with RIPE NCC, originates 1,011 IPv4 prefixes covering 1.5M addresses and 234 IPv6 prefixes. By IPv4 address space that makes it the 356th-largest of the 79,516 networks we see originating IPv4, and the largest of 669 in Bulgaria. It is seen behind 48 upstream networks, most often AS3356 (Lumen (Level 3)) and AS9002 (RETN Limited), and in front of 110 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 98% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Upstream graph

The networks AS8866 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS8866 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.
