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  • The details registered about me/my company are incorrect or out of date.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

ISP's, SURFnet and SIDN ready for the war against botnets

  • Friday 10 October 2014

AbuseHUB, the Dutch internet service providers’ shared system for tackling botnets, became formally operational today. Following a successful development and testing programme, the system is now all ready for use. The stakeholders accordingly gathered in Amersfoort this morning to celebrate the conclusion of the development phase.

Extended version of the AbuseHUB

Since the prototype version of AbuseHUB went live in November last year, the development team has been hard at work extending the systems and incorporating additional sources of information about botnet infections. As a result, the system now being rolled out has been comprehensively tested and is able to draw on valuable data from all over the world, maximising the capability to respond quickly and effectively to botnet infections.

Number of infections is high and rising

Botnets are networks of computers that, unknown to their owners, have been infected with a virus or other malware, enabling someone else to control them. Botnets are widely used for sending spam and mounting cyber-attacks. In most cases, botnet software barely affects the infected computer. Consequently, the owners are often unaware that anything is wrong. However, the activities of botnets can cause a lot of harm and inconvenience to others. Research by Delft University of Technology suggests that, over a year, between 5 and 10 per cent of consumers in the Netherlands suffer a botnet infection. The AbuseHUB partners are determined to get that figure down.

Strong response

AbuseHUB is an initiative by the Abuse Information Exchange, a platform on which KPN, RoutIT, SIDN, SOLCON, SURFnet, Tele2, UPC, XS4ALL, ZeelandNet and Ziggo all work together. The AbuseHUB collates, analyses and sorts botnet infection reports and sends the findings to the affiliated organisations. So the internet service providers have an up-to-date picture of reported infections in their networks, enabling them to work with their customers on swift, targeted action to deal with the infections.

Data sources: cooperation with NCSC

AbuseHUB obtains information about infections from various sources in the Netherlands and elsewhere. The information providers are known as ‘reliable notifiers’, because prior to acceptance they are carefully screened to verify the reliability of their information. The Abuse Information Exchange is currently talking to the Dutch National Cyber Security Center (NCSC) about the possibility of the Center supplying data to the AbuseHUB.
