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  • The details registered about me/my company are incorrect or out of date.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.

Protecting your domain name

Your domain name is valuable – financially or emotionally. So naturally you want to protect it. We offer two extra protection options: DNSSEC and .nl Control.

Protecting your domain name with DNSSEC

secure .nl
DNSSEC .nl Control Security of .nl

DNSSEC prevents fraudsters diverting your visitors to phishing sites or intercepting your mail. For details, go to our DNSSEC page.

How do I get DNSSEC?

DNSSEC is arranged through your registrar (hosting service provider). Not all registrars support DNSSEC. To see which ones do, look at our Registrar list and tick the box Show only those that support DNSSEC.

Protecting your domain name with .nl Control

Our .nl Control service maximises your control over your domain name. Once you're signed up, no significant change can be made without your permission (or your representative's permission). So the chances of something being changed by mistake or by mischief are much smaller. For details, go to our .nl Control page.

How do I get .nl Control?

You need to apply through your registrar. There are extra fees to pay for .nl Control. Exactly how much it costs varies from registrar to registrar.
