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  • The details registered about me/my company are incorrect or out of date.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

New features for SIDN BrandGuard Q1 2023

A short guide to the main improvements

  • Thursday 9 March 2023

Over the last three months, we've released multiple new versions of SIDN BrandGuard incorporating a range of improvements. Some functional changes were requested by subscribers, and we made other changes to improve performance, convenience and security.

Enhanced security

We have enhanced the security of SIDN BrandGuard by adding 2FA and access tokens. The new 2FA set-up follows the time-based one-time password (TOTP) principle. What you do is link a TOTP app, such as Google Authenticator or Microsoft Authenticator, to your user account. Then, each time you access the service, the app generates a code, which you enter as part of the login process. The security of the API has been upgraded as well, by the introduction of access tokens. You can manage your 2FA and access tokens under 'Settings'.

For the time being, you can still log in the traditional way. In due course, however, we intend to make 2FA mandatory for web access and tokens mandatory for API access.

Functional improvements

We have made a number of functional improvements, including the following:

Logos in e-mail notifications

If we detect a logo that looks like yours, an image is now included in the notification e-mail. So you don't need to log in to check out the detection.

Feedback on logo detections

If we detect a logo that looks like yours, you can now give feedback on the detection. We'll then use your feedback for continuous training and improvement of the AI model that performs the logo recognition.

You can also open a report on a new tab. On a Windows-based system, you can do that by holding the Ctrl key down and clicking on the relevant report.

Performance improvements

We've improved the performance of the logo filtering and logo display functions. In some cases, the system now responds 35 times faster.

Bug fix

There was previously an issue that affected filtering by registrant name or by name server. That's now been fixed.
