As of 27th September 2026, AS21221 (Infopact Netwerkdiensten B.V.), an access network registered in the Netherlands with RIPE NCC, originates 20 IPv4 prefixes covering 101k addresses and 7 IPv6 prefixes. By IPv4 address space that makes it the 2,371st-largest of the 79,523 networks we see originating IPv4, and the 32nd-largest of 1,023 in the Netherlands. It is seen behind 30 upstream networks, most often AS174 (Cogent Communications, LLC) and AS20562 (Open Peering (Broadband Hosting B.V.)). Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 96% of its routes reach at least 90% of full-feed peers, and 1 prefix is also originated by another network.

Networks observed one and two hops upstream of AS21221 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.
