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  • The details registered about me/my company are incorrect or out of date.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

Fraudehelpdesk and SIDN start threat intelligence pilot

SIDN Labs has teamed up with Fraudehelpdesk to run an innovative pilot scheme. From 1 November, the two organisations will be sharing information about domain names suspected of being used for phishing. The aim is to explore the potential that threat intelligence sharing has for speeding up the process of identifying sources of phishing mail and taking infected .nl websites off line.

At the heart of the pilot is a technical interface between two big data systems: SIDN Labs' ENTRADA and Fraudehelpdesk's APATE (APATE). When Fraudehelpdesk receives a new report of abuse (step 1 in the diagram below), they will let us know about any .nl domain name involved (step 2). Our system will respond automatically by sending back the following information about the domain name's query history and registrant (step 3):

  • The number of DNS queries received for the domain name in the last seven days

  • The registration date of the domain name

  • Whether the registrant is based outside the Netherlands (yes/no)

  • The registrar's pseudonym

Step 3 is covered by a privacy policy in line with our ENTRADA privacy framework.Project workflow1. User reports suspicious e-mail2. FHD passes on .nl domain name3. Additional info about suspect domain name4. Classification and prioritisation of e-mail5. Phishing!We believe that the link-up with ENTRADA will help Fraudehelpdesk to establish more quickly whether a domain name is being used for phishing. That in turn will improve the process of prioritising reports (step 4). Wherever phishing is confirmed, Fraudehelpdesk will publish details on their website and in their social media feeds (step 5). Here at SIDN Labs, we'll receive feedback from Fraudehelpdesk about the number of reports and their APATE classification. That information should enable us to improve our own phishing detection mechanisms, such as NDEWS. Fraudehelpdesk and SIDN Labs are making a joint presentation about the project at the ECP Annual Congress on Thursday 17 November. The slides will be published on SIDN Labs - publication.
