As of 11th November 2026, AS35628 (Institute of Bioorganic Chemistry…), a network registered in Poland with RIPE NCC, originates 3 IPv4 prefixes covering 768 addresses. By IPv4 address space that makes it the 45,669th-largest of the 80,743 networks we see originating IPv4, and the 975th-largest of 2,109 in Poland. It is seen behind 1 upstream network, most often AS5617 (Orange Polska Spolka Akcyjna), and in front of 6 downstream networks. None of its announcements have a valid RPKI ROA. 0% of its routes reach at least 90% of full-feed peers.

Networks observed one and two hops upstream of AS35628 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.
