As of 27th September 2026, AS13293 (Institute of Bioorganic Chemistry…), a network registered in Poland with RIPE NCC, originates 5 IPv4 prefixes covering 1.3k addresses and 1 IPv6 prefix. By IPv4 address space that makes it the 33,367th-largest of the 79,525 networks we see originating IPv4, and the 667th-largest of 2,096 in Poland. It is seen behind 2 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS174 (Cogent Communications, LLC), and in front of 20 downstream networks. None of its announcements have a valid RPKI ROA. 100% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS13293 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.
