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  • The details registered about me/my company are incorrect or out of date.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

Dutch king to discuss the security of the .nl domain and the future of the internet with SIDN

Willem-Alexander to make a virtual working visit on 16 November

King Willem-Alexander, King of the Netherlands
  • Tuesday 19 October 2021

His Majesty the King will pay SIDN a virtual working visit on the morning of Tuesday 16 November to mark the twenty-fifth anniversary of SIDN taking over management of the .nl domain. The .nl domain itself has been in existence for thirty-five years. When the first .nl domain name was registered in 1986, the Dutch national domain became the first active country-code domain outside the US. With more than 6.2 million domain names, .nl is today one of the biggest and most secure country-code domains in the world.

SIDN's role

SIDN registers .nl domain names and ensures that they are reachable. We also conduct research into new technologies that promote the security and stability of the .nl domain and the internet infrastructure. We work on solutions in the field of cybersecurity and digital identities to make using the internet more convenient and secure, and we support initiatives that promote use of the internet and mitigate its negative side-effects.

The King in conversation with SIDN

The king will talk to SIDN staff about SIDN's history and the .nl domain's development, and hear about the work being done to maintain the security of .nl and assure the continuous availability of the domain. The king will then have a discussion with stakeholders regarding the prevention of internet crime and unlawful activities involving .nl domains, as well as projects that help make the internet stronger and more secure. The virtual working visit will conclude with a talk about possible improvements to the internet and the digital infrastructure of the future, and about strategies for assuring quality, security and privacy as both the internet user population and the intensity of internet use continue to grow.
