AS60781 LeaseWeb Netherlands B.V.
Every prefix the ASN database assigns to AS60781, the operator behind it, the registry that allocated the system and when, and what the operator lists say about it. Facts about a network, read from data held on this server — never about whoever is using an address today.
The system at a glance
| Number | AS60781 |
|---|---|
| Operator | LeaseWeb Netherlands B.V. |
| Operator type | a hosting or cloud operator |
| Registry | RIPE NCC |
| Registry country | NL |
| Allocated | 2013-05-13 |
| Prefixes | 303 IPv4, 166 IPv6 |
| Threat blocklist | not listed |
| Satellite ISP | not listed |
| Mobile carrier | not listed |
The flags are what the lookup applies to every address of the system: Spamhaus ASN-DROP names operators behind hijacked or leased netblocks, and the satellite and mobile lists are curated and positive-only, so "not listed" means exactly that and never a guess.

The same facts from the API
One call answers the operator, the registry facts, the flags, the prefix counts and up to 500 prefixes per family, 469 in total for this system. It costs one credit, and a repeat inside seven days is free.

-H "Authorization: Bearer $SPAW_KEY"How to read this page
The prefixes are what the free DB-IP ASN database assigns to the system, walked once a month into an index on this server — a database, not a live route table, so a prefix announced yesterday appears at the next build. The registry facts are the regional registries' own daily statistics. None of it says who is behind an address today: a carrier's prefix carries thousands of people, and a hosting operator's carries whatever its customers run.
