As of 26th September 2026, AS1136 (KPN B.V.), an access network registered in the Netherlands with RIPE NCC, originates 425 IPv4 prefixes covering 7.4M addresses and 15 IPv6 prefixes. By IPv4 address space that makes it the 98th-largest of the 79,516 networks we see originating IPv4, and the 3rd-largest of 1,023 in the Netherlands. It is seen behind 18 upstream networks, most often AS2914 (NTT America, Inc.) and AS6830 (Liberty Global Europe Holding B.V.), and in front of 22 downstream networks. 95% of its announcements have a valid RPKI ROA, and none are RPKI-invalid.

Networks observed one and two hops upstream of AS1136 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.
