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  • The details registered about me/my company are incorrect or out of date.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

SIDN and RA team up to give hosting firms insight into the security status of their platforms

By launching the Hosting Infrascan, the two organisations aim to help the hosting sector make the internet more secure

In order to maximise and maintain the security of their technical infrastructures, hosting service providers need a clear picture of any weak spots. That implies performing or commissioning large-scale hosting platform scans to detect vulnerabilities. Unfortunately, such scans are expensive and consequently uneconomical for many firms. SIDN, the Registrars' Association and ThreadStone have therefore linked up to create the Hosting Infrascan. The scan provides hosting service providers with the security status information they need.

Working together to make .nl secure

"There's more to keeping the .nl domain secure and trustworthy than making sure that our own technical infrastructure is sound," says SIDN's CEO Roelof Meijer. "It's vital that the platforms where .nl domain names and websites are hosted are secure as well. Many .nl registrars or their resellers provide hosting services. The Hosting Infrascan is designed to help them identify weak spots, so that issues can be resolved. Because we're committed to keeping the .nl domain as secure as possible, we're covering the bulk of the cost."

Collaboration between SIDN and the RA

"Since 2018, SIDN has been investing some of the income from .nl in projects that enhance the domain, while also benefitting .nl registrars," explains Xander Slootweg, Managing Director of Internet Today and Registrars' Association Board member. "The projects are co-creations of the RA and SIDN. The Hosting Infrascan is one of the products of that teamwork, like the SIDN Academy and the Legal Help Desk for .nl registrars."

User-friendly dashboard

The Hosting Infrascan is carried out by ThreadStone. Working from IP address lists provided by hosting firms, ThreadStone checks out each platform's servers and firewall. Details of all the vulnerabilities detected are then shared with the hoster. That might include issues with SSL certificates, firewall ports that shouldn't be open but are, outdated operating systems and so on. The scan results are presented on a user-friendly personalised dashboard, and hosting firms can also call on support from ThreadStone's certified ethical hackers. .nl registrars and hosting service providers can get more information or register for the service at www.hostinginfrascan.nl.
