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  • The details registered about me/my company are incorrect or out of date.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

Big rise in IPv6-enabled domain names

  • Tuesday 30 January 2018

Around the world, IPv6 is on the up. And, although the trend was a slow-starter in the Netherlands, the number of IPv6-enabled .nl domain names has more than doubled in the last six months. Over one and a half million of them can now be reached using the new protocol. We hope to see the figure up around two million by the end of the year.

Switch to IPv6 has to happen

Internet.nl

IPv6 is the successor to IPv4, the established internet addressing protocol. A new protocol is needed for the simple reason that the internet is now so big that there just aren't enough IPv4 addresses to give every connected device a unique ID. The shortage has been causing problems for a while. Migration to IPv6 has to happen, and we want to support it.

Why updating is important

A global total of three billion people now use the internet. Often for privacy-sensitive, high-value transactions. Yet legacy internet standards date from the seventies and eighties, when user numbers were a fraction of what they are today. Those standards aren't sufficiently scalable and don't meet modern security requirements. If we want the internet to remain reliable, we have to start using smarter modern standards. A whole generation of new internet standards is coming on stream, and IPv6 is one of them.

Rewards pay!

Our Registrar Scorecard (RSC) exists to encourage registrars to help build a better, safer internet.

The RSC is an incentive scheme, through which we reward registrars for contributing to the quality of the .nl zone. We currently scan RSC members' domain name portfolios for several quality determinants: the combination of active domain name use and low cancellation rate (actively used domain names being less likely to get cancelled), registration data quality and support for DNSSEC. For the last six months, we've additionally been rewarding registrars that have a lot of IPv6-enabled domain names in their portfolios. And the policy is working! The number of domain names that can be reached using IPv6 has more than doubled since the rewards came in.
