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  • The details registered about me/my company are incorrect or out of date.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

iB Informatiebeveiliging -- the magazine of the Platform for Information Security -- has published an interview with concept developer Bart Jacobs and our CEO Roelof Meijer, in which they discuss the IRMA authentication app. Read more about the principles underpinning IRMA, how it works and the future of digital identities.

Introduction

Ever been asked to show your ID for something trivial? Or told by a car hire firm that they need a copy of your passport? Maybe made to create a detailed user profile to access a website? You're not alone! And Bart Jacobs, Professor of Computer Security, Privacy and Data Management at Nijmegen's Radboud University reckons that kind of thing is crazy. He thinks you should never share more personal data (attributes) than strictly necessary.

And that's the principle underpinning the app he developed: IRMA ('I Reveal My Attributes'). As Bart says, IRMA is an app that lets you "securely prove who you are, without giving away too much about yourself".

Growing consumer awareness offers hope

Meijer derives hope from the research finding that more and more people agree with the statement, "I want to decide what data I share and don't want to share more data than I have to." He believes that, slowly but surely, we're becoming more aware that we need to be more careful with our data than we have been in the past. "If consumers start asking for more control, webshops will be able to gain a competitive advantage by offering convenient and secure logins," Meijer concludes.

"With IRMA, we want to make it clear that you do have a choice," says Roelof Meijer.
