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  • The details registered about me/my company are incorrect or out of date.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

Meet SIDN at Holland Strikes Back

  • Monday 25 September 2017

The internet has become an all-embracing feature of everyday life. More and more people are using the internet, and using it more intensively. The possibilities are increasing all the time. So it's vital that people can have confidence in the internet's quality, security and privacy. But, unfortunately, cybercrime is becoming more and more sophisticated, with data thefts, privacy breaches, fake news and more besides.

So the fourth edition of Holland Strikes Back on 4 October will be focusing on ways of countering the risks. The event aims to provide visitors with the insight, knowledge and tools they need to defend themselves against cybercrime. SIDN will be at Holland Strikes Back to give a fascinating presentation and demo on security and privacy on home networks.

SPIN: Security and Privacy for In-home Networks

Exciting new devices with amazing potential are being enabled by the Internet of Things. The associated security aspects are often seen as a side issue, however. As a result, problems such as large-scale DDoS attacks are increasingly common. Our SPIN project has been started to look at ways of tackling such attacks at source: in the home networks hijacked to launch them. With SPIN, we want to contribute to the security of the whole internet, including DNS operators such as SIDN and our registrars. While also giving users more control over their privacy and security on the Internet of Things.

Presentation en demo

Jelte Jansen from SIDN Labs will be making his presentation between 14:05 and 14:25, during the plenary session. He'll be giving a preview of SPIN's goal: an open-source platform for tackling IoT-powered DDoS attacks from home networks and giving users more control over their security and privacy. After the presentation, from 14:30 to 14:55, Marco Davids will give a more comprehensive demonstration of the SPIN system and how it works.

At both sessions there'll be opportunity to ask questions and give feedback, which we always welcome. Everyone from SIDN will also be happy to chat during the refreshments :-). And, if you can't catch up with us at the event, you can always drop a line to labs@sidn.nl.
