As of 26th September 2026, AS6876 (TENET Scientific Production Enterprise…), an access network registered in Ukraine with RIPE NCC, originates 31 IPv4 prefixes covering 112k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 2,243rd-largest of the 79,516 networks we see originating IPv4, and the 16th-largest of 1,521 in Ukraine. It is seen behind 37 upstream networks, most often AS174 (Cogent Communications, LLC) and AS28917 (Fiord Networks, UAB), and in front of 5 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS6876 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.
