PolandRegistryRIPE NCC

As of 10th November 2026, AS9141 (P4 Sp. z o.o.), a network registered in Poland with RIPE NCC, originates 76 IPv4 prefixes covering 1.6M addresses and 13 IPv6 prefixes. By IPv4 address space that makes it the 337th-largest of the 80,723 networks we see originating IPv4, and the 2nd-largest of 2,108 in Poland. It is seen behind 2 upstream networks, most often AS1299 (Arelion (fka. Telia Carrier)) and AS3356 (Lumen (Level 3)), and in front of 71 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 AS9141 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.
