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The details registered about me/my company are incorrect or out of date.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.
Everyone wants to feel safe when they use the internet. Whether you go on line to play, watch, shop or read, you shouldn't have to worry about what might happen. So we work hard every day to make our part of the internet, the .nl domain, as secure as we possibly can.
Keeping .nl secure is specialist work. So we invest a great deal in recruiting and training people to do that job. And we encourage them to participate in national and international working groups to increase their knowledge. That means involvement in forums and organisations such as ICANN, CENTR, IETF, RIPE and NCSC.
We have a special incident investigation team
The Computer Security Incident Response Team investigates all security breaches: events where a computer system may have been hacked. The team also keeps us on our toes where the protection of our systems is concerned.
Websites and computers sometimes get hit by DDoS attacks. That's where thousands of computers are made to visit a site or access a system, all at the same time. The attackers hope that the site or system will crash under the load. We therefore have a distributed server set-up, so that we can fight off that kind of assault without you noticing. The technology we use is called anycast.
We exchange information about abuse
We belong to the Abuse Information Exchange, where we work with service providers to keep each other informed about problems. We are also active in abuse prevention. So, if ever your domain name is used for abuse, we'll alert you. We do that through a scheme called Abuse204.nl ('abuse to zero for .nl').
We have a research and development team called SIDN Labs, which develops new technologies and systems to boost the stability and safety of .nl and the DNS, for example.
We work with NLnet Labs, SURFnet, TNO and others on the development of new internet technologies.
We also have research partnerships with universities and other knowledge centres.
We do lots of research and development
We have close links with the National Cyber Security Centre
The National Cyber Security Centre is part of the Dutch Ministry of Security and Justice. We share our knowledge with the Centre.
We have ISO-certified information security
Our information security arrangements are certified to ISO 27001. That means meeting strict requirements set by the International Organization for Standardization in order to get our certificate renewed each year. So we have to maintain a constant focus on the security of the data we manage.
