NetherlandsRegistryRIPE NCCTypeEyeballAs of 26th September 2026, AS8737 (KPN B.V.), an access network registered in the Netherlands with RIPE NCC, originates 6 IPv4 prefixes covering 49.2k addresses. By IPv4 address space that makes it the 4,500th-largest of the 79,516 networks we see originating IPv4, and the 67th-largest of 1,023 in the Netherlands. It is seen behind 2 upstream networks, most often AS1136 (KPN B.V.) and AS64416 (Critical Core BV), and in front of 1 downstream network. 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 3 prefixes are also originated by another network.

Upstream graph
The networks AS8737 is seen behind, one and two hops out, drawn from real AS paths.
Networks observed one and two hops upstream of AS8737 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.
