AS60781

AS60781 is LeaseWeb's Amsterdam network, registered under RIPE to LeaseWeb Netherlands B.V., part of a large Dutch dedicated-server, hosting, and IaaS group. PeeringDB classifies it as a Content network with heavy-outbound traffic, and it peers via the group's core ASN AS16265 (LeaseWeb Network B.V.). It announces roughly 466–478 IPv4 prefixes and ~197–334 IPv6 prefixes (~438,460 IPv4 addresses), with transit including Arelion plus connectivity through AS16265, Cogent, and Level3; CAIDA ranks it #12637 as a single-ASN cone. The LeaseWeb brand is unusually fragmented across registries — roughly thirteen ASNs spanning North America (AS7203, AS30633, AS394380, AS395954, AS32613), Europe (AS28753 LeaseWeb Deutschland, AS60781, AS205025, AS205544), APAC (AS59253, AS133752, AS136988, AS134351), a CDN ASN (AS60626), and the core AS16265 — so the first triage step is identifying which sibling ASN and country a given IP actually sits in before attributing anything. As multi-tenant dedicated hosting the usual caveat applies: attribute behavior to the tenant, not the operator.
