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  • The details registered about me/my company are incorrect or out of date.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 BrandGuard update Q4 2023

BrandGuard now scans behind cookie walls

  • Thursday 30 November 2023

Over the last few months, our development team has been working to refine SIDN BrandGuard and fix a number of bugs. We've also resolved a couple of problems with 2-factor authentication. The main improvements are outlined below, along with a final reminder to enable 2-factor authentication.

For its logo detection and threat assessment functions, SIDN BrandGuard scans all websites in the .nl zone. And we've recently enhanced BrandGuard's scanning capabilities by enabling the scanner to click through full-screen cookie walls in order to scan the pages concealed behind them. The enhancement means increased scan reach and more effective logo detection.

Improved logo detection performance

In the latest release, a new, more modular logo detection architecture has been adopted, making it quicker and easier for us to add or change logos without affecting existing scans. The result is significantly improved performance and faster result reporting.

Bug fixes

Various SIDN BrandGuard bugs have recently been fixed. The main problems we've addressed are:

  • The new user creation process sometimes failed

  • 2FA sometimes didn't work with Microsoft Authenticator

  • In the API, page numbers weren't always displayed correctly

  • The search bar wasn't displayed correctly in some cases

  • The boxes highlighting detected logos weren't always displayed correctly for web interface users

All those issues have now been fixed.

2FA mandatory from the start of January

Although it's still optional for now, 2FA will be mandatory from the start of 2024. Almost all SIDN BrandGuard users have already enabled 2FA, but a few have yet to do so. If you're one of those that haven't switched on 2FA, please do so before the end of the year.
