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  • The details registered about me/my company are incorrect or out of date.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

  • Monday 25 October 2021

Yes! This year, we're allowed to meet face-to-face again at SIDN Inspire, which is scheduled for Wednesday 1 December 2021.

If you're not able to make it to Utrecht, you'll have the option of following proceedings online.

UPDATE: SIDN Inspire has been moved to 25 May 2022

A key element of this year's SIDN Inspire will be the .nl domain's thirty-fifth anniversary. The anniversary is an excellent opportunity for reflection, but especially for looking ahead. The theme of the gathering will therefore be the future of the internet. Programme A full afternoon of activities is planned, with two inspiring keynote speakers, a panel discussion and an opportunity for networking over a drink at the end. Here's a little preview of what you can expect... Ruben Verborgh Our first keynote speaker is Ruben Verborgh, Professor of Decentralised Web Technology and a member of the team behind Solid, the new initiative by Tim Berners-Lee, inventor of the World Wide Web. Ruben will be talking about decentralised data storage and data autonomy. We live in a data-driven society and economy. Decades of Big-Data thinking have created an environment where it's assumed that a business has to collect personal data in order to avoid being left behind in the data-focused technology race. During his keynote speech, Ruben will explain how we, the data subjects, can regain control of our data in such an environment. Expert panel We'll be exploring the future internet theme – as well as topics of business, technology and cybersecurity – with the help of a panel of experts, including Sander Duivestein, trend-watcher and author of 'Echt nep' ('Genuinely fake'), Inge Bryan, Managing Director of NCC Europe at Fox-IT, Cristian Hesselman, Director of SIDN Labs, and Lotte de Bruijn, Director of NLdigital. Jim Stolze We'll close the main proceedings with an inspiring keynote speech by Jim Stolze. Jim will be talking about AI solutions and providing insight into how models are trained, what they're capable of and where the challenges lie. He'll also take you through the ethical dilemmas associated with AI and how we can protect ourselves against unsolicited and undesirable algorithmic interference in our lives. Register now! Block out 1 December in your diary for the opportunity to experience an unforgettable afternoon of inspiring insights into the developments shaping the future of the internet.
