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  • The details registered about me/my company are incorrect or out of date.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 .nl registrars support Cybersecurity Month in October

Working together to make the internet safer in the Netherlands

  • Monday 26 September 2022

From 3 to 31 October, activities will be taking place throughout the Netherlands as part of European Cybersecurity Month, overseen by the Alert Online partner network. As in previous years, we'll be supporting Cybersecurity Month by organising and sponsoring activities, making content available, and sharing other campaign partners' content. This year, we'll also be working with nl. registrars to raise registrants' awareness of the scope for making websites and e-mail more secure. That'll involve a new campaign, where examples from everyday life are used to encourage smaller businesses to talk to their service providers about website and mail security.

What is Cybersecurity Month?

The aim of the annual Cybersecurity Month is to promote the cyber-resilience of businesses, public service providers and the wider community. The Dutch campaign is organised by the Alert Online platform: a network set up by the Ministry of Economic Affairs and Climate Policy, whose members include SIDN, the Dutch Banking Association, Thuiswinkel.org, Microsoft and Google. In October, all the partners will be organising events, training courses and exercises to get their personnel, customers and contacts thinking about cybersecurity.

Secure websites and mail

Central to SIDN's communications will be the role that registrars and hosting service providers can play in making websites and mail traffic more secure. The scope for improvement is greatest in the small-and-medium-sized business sector, because SMEs understandably find it harder to give security the attention it deserves. The campaign will therefore aim to nudge SMEs into talking to their hosting service providers or registrars about risks and solutions, including:

  • Open security standards for websites (e.g. DNSSEC) and e-mail (e.g. DMARC)

  • TLS certificates

  • Private clouds

  • Multi-factor authentication and secure login solutions

  • Server and application vulnerability detection

Everyday examples

The joint campaign will feature banners and social posts that use examples from everyday life to get people thinking about security. Audience members will be encouraged to contact their hosting service providers or registrars for help making their websites and e-mail more secure. Here are a few specimen posts:
