About SIDN

SIDN (the Foundation for Internet Domain Registration in the Netherlands) is the registry for .nl domain names. It has been managing the .nl domain – that is, all internet domain names that end in ‘.nl’ – since 1996. As well as registering and issuing domain names, SIDN ensures that the domains can always be reached by internet users everywhere.

.nl – the world’s number one
SIDN looks after almost four million .nl domain names. That’s more than one domain name for every five people in the Netherlands – making .nl the world’s number one. Registration services are made available to the public through nearly two thousand independent commercial registrars.

Leading role
SIDN is actively involved in the internet’s technical, policy and political development, at the national and international levels. SIDN played the lead role in introducing DNSSEC and ENUM to the Netherlands, for example.
