PolandRegistryRIPE NCC

As of 27th September 2026, AS41079 (Cyber_Folks S.A.), a network registered in Poland with RIPE NCC, originates 23 IPv4 prefixes covering 15.1k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 8,453rd-largest of the 79,516 networks we see originating IPv4, and the 108th-largest of 2,096 in Poland. It is seen behind 2 upstream networks, most often AS15694 (Atman Sp. z o.o.) and AS58321 (Oxylion Sp. z o.o.). 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, and 2 prefixes are also originated by another network.

Networks observed one and two hops upstream of AS41079 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.
