AS196844Institute of Bioorganic Chemistry Polish Academy of Science, Poznan Supercomputing and Networking Center
As of 11th November 2026, AS196844 (Institute of Bioorganic Chemistry…), a network registered in Poland with RIPE NCC, originates 3 IPv4 prefixes covering 768 addresses and 1 IPv6 prefix. 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 37 upstream networks, most often AS7713 (PT Telkom Indonesia Tbk) and AS18106 (Viewqwest Pte Ltd), and in front of 33 downstream networks. None of its announcements have a valid RPKI ROA. 0% of its routes reach at least 90% of full-feed peers.

Upstream graph
The networks AS196844 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS196844 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.
