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  • The details registered about me/my company are incorrect or out of date.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 Inspire 2024: working together to achieve more

Watch our short video compilation

  • Thursday 23 May 2024

On Thursday 16 May, the fourth edition of SIDN Inspire was held at LIEMÈS in Utrecht: a new venue where connection and togetherness found culinary expression. Because we can achieve more together than alone, the theme of the event was 'Forward together'.

Keynote presentation Gina Doekhie – cybercrime specialist

The programme featured a succession of interesting speakers, including cybercrime specialist and digital detective Gina Doekhie. In her keynote presentation, Gina spoke about the importance of collaboration amongst the police, private enterprises and victims. She illustrated how cybercriminals operate using practical examples, described the latest developments in the world of cybercrime, and considered the use of AI and the threat it poses.

In-depth sub-sessions

Following Gina's keynote presentation, guests were able to choose from a number of sub-sessions. This year's options included a sub-session on the theme of domain names, arranged in collaboration with the RA. Berend van Dalfzen talked about the current situation within the domain name industry, sharing the latest data, identifying trends and highlighting notable developments. Berend also took a closer look at the new ICANN contract for gTLDs, and considered its implications for the market. His co-presenter Siemen Roorda brought the sub-session to a close by looking at the upcoming gTLD application window scheduled to open in 2026.

Lawyer Thomas Rickert, who is Managing Partner at Rickert.law, led another sub-session this year, updating guests regarding NIS2 and its impact on the EU's domain name industry.

SIDN Labs' Research Engineer Elmer Lastdrager made a presentation on post-quantum cryptography (PQC). Topics covered included some of the challenges to be overcome and the progress of SIDN Labs' initiative to set up a testbed for PQC in the DNS.

Hester Benedictus, policymaker and inventor of the Lees Simpel app made an interactive presentation explaining how the app was designed and how it works. Hester also considered how AI can help organisations to write better letters.

Technophilosophy with Rens van der Vorst

Finally, technophilosopher Rens van der Vorst wound up proceedings with a humorous presentation exploring the question "How do we stay human in the era of digital technology?" His message was that everyone should be more of a digital gremlin. ;-)

The day was brought to an enjoyable close with refreshments and a delicious walking dinner that confirmed LIEMÈS's reputation as Utrecht's food district.
