NetherlandsRegistryRIPE NCCTypeCarrier

As of 26th September 2026, AS38930 (LeaseWeb (fiberring)), a transit carrier registered in the Netherlands with RIPE NCC, originates 6 IPv4 prefixes covering 10.5k addresses and 2 IPv6 prefixes. By IPv4 address space that makes it the 10,200th-largest of the 79,516 networks we see originating IPv4, and the 152nd-largest of 1,023 in the Netherlands. It is seen behind 5 upstream networks, most often AS8283 (Netwerkvereniging Coloclue) and AS1299 (Arelion (fka. Telia Carrier)), and in front of 19 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 AS38930 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.
