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  • The details registered about me/my company are incorrect or out of date.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

Technical webinar: How you can use big data to improve the security and stability of the internet

  • Monday 30 October 2017

During this technical webinar, which is from 3pm to 4pm (Dutch time) on Wednesday 15 November, we'll show you how SIDN Labs uses big data to make the internet more secure in the Netherlands and beyond. When cyber criminals use the DNS, we're able to spot their activities by analysing the DNS queries handled by our .nl name servers. We'll be explaining how we do that and how you can do it too.

Speakers

  • Moritz Müller, Research Engineer at SIDN Labs, will be looking at abuse countermeasures based on data analysis. Our authoritative name servers get about 1.3 billion DNS queries a day. Unfortunately, not all of them are legitimate. Some originate from botnet clients and other malicious sources. Picking them out can be hard, partly because of the complexity of the DNS.

  • Maarten Wullink, Research Engineer at SIDN Labs, will be talking about the ENTRADA big data platform that SIDN Labs has developed. (ENTRADA stands for ENhanced Top-level domain Resilience through Advanced Data Analysis.) He'll explain what ENTRADA is and how it works. Together with Moritz, he'll also be presenting a number of interesting case studies involving initiatives such as nDEWS: a monitoring system that uses the DNS infrastructure for early detection of malicious domain names. 

  • Sebastiaan Assink, Key Account Manager at SIDN, will chair the webinar. He'll be putting questions to Moritz and Maarten to clarify how ENTRADA could be useful to registrars. You'll be able to ask your own questions using the webinar chat facility, and they'll be dealt with live.

      

Follow-up session

After the webinar, we plan to assess the appetite for exploring this topic in more depth. If there's enough interest, we'll organise a practical follow-up workshop at our offices.
