Frequently asked questions

  • I am looking for a domain name registrant. Where can I look it up?

    The Whois is an easy-to-use tool for checking the availability of a .nl domain name. If the domain name is already taken, you can see who has registered it.

    On the page looking up a domain name you will find more information about what a domain name is, how the Whois works and how the privacy of personal data is protected. Alternatively, you can go straight to look for a domain name via the Whois.

  • I would like to transfer my domain name to another registrar. What is the procedure?

    To get your domain name transferred, you need the token (unique ID number) for your domain name. Your existing registrar has the token and is obliged to give it to you within five days, if you ask for it. The procedure for changing your registrar is described on the page transferring your domain name.

  • The details registered about me/my company are incorrect or out of date. How can I get them updated?

    To update the contact details associated with your domain name, you need to contact your registrar. Read more about updating contact details.

  • Why is my domain name in quarantine?

    When a domain name is cancelled, we aren't told the reason, so we can't tell you. You'll need to ask your registrar. The advantage of quarantine is that, if a name's cancelled by mistake, you can always get it back.

    One common reason is that the contract between you and your registrar says you've got to renew the registration every year. If you haven't set up automatic renewal and you don't renew manually, the registration will expire.

  • Ik heb een klacht over mijn provider/registrar. Kan ik daarvoor bij SIDN terecht?

    Wanneer je een klacht hebt over of een geschil met je registrar dan zijn er verschillende mogelijkheden om tot een oplossing te komen. Hierover lees je meer op pagina klacht over registrar. SIDN heeft geen formele klachtenprocedure voor het behandelen van een klacht over jouw registrar.

  • What conditions do I have to meet as a registrar?

    Would you like to be able to register domain names for customers or for your own organisation by dealing directly with SIDN? If so, you can become a .nl registrar. Read more about the conditions and how to apply for registrar status on the page becoming a registrar.

Preventing abuse to keep .nl secure

Over the years, we've taken various steps with the aim of actively tackling or helping to tackle abuse on the internet and within the .nl domain.

How we see our role in abuseprevention

We've also developed a vision of our role in the prevention of abuse in the .nl domain. Central to our vision is the conviction that our position as operator of the .nl domain implies playing an active role in efforts to prevent improper practices within the .nl zone.

Transparency report

Compared with the total number of .nl domains - more than six million - the number of times we intervene is very small. Nevertheless, we think it's important to be open and transparent about our interventions, because they can have major implications for those involved. Here you'll find details about how often we have felt obliged to take action or share information, of our own accord or in response to legal proceedings.

Promoting modern internet standards

We promote modern internet standards

In order to keep the internet safe and stable, we work with the Platform for Internet Standards to encourage the use of modern internet standards. The Platform is a joint initiative by the Dutch business community and government to promote open standards such as IPv6 (the new IP addressing protocol), DNSSEC (for safe data transport), TLS (for safe encryption), and DMARC, DKIM and SPF (for e-mail security against spam and phishing). Simply check via internet.nl whether your website complies with the modern internet standards.
