Summary

SIDN (.nl registry)

Netherlands · AI-generated

enterprise legacy

SIDN (Stichting Internet Domeinregistratie Nederland), the foundation that

operates the .nl country-code top-level domain, one of the largest ccTLDs in

the world.

What it's used for

  • Running the registry and DNS infrastructure for .nl domain names.

Notable

  • Critical national internet infrastructure run by a not-for-profit foundation, not a commercial ISP or host. The low AS number reflects an early RIPE-region allocation.
