As of 27th September 2026, AS42555 (OPTICCOM- BULGARIA Ltd.), an access network registered in Bulgaria with RIPE NCC, originates 25 IPv4 prefixes covering 12k addresses. By IPv4 address space that makes it the 9,613th-largest of the 79,523 networks we see originating IPv4, and the 58th-largest of 669 in Bulgaria. It is seen behind 7 upstream networks, most often AS6461 (Zayo Bandwidth) and AS174 (Cogent Communications, LLC), and in front of 6 downstream networks. None of its announcements have a valid RPKI ROA. 96% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS42555 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.
