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  • The details registered about me/my company are incorrect or out of date.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

Government and suppliers make joint push for further IPv6 adoption

  • Tuesday 12 November 2019

All government bodies in the Netherlands must be reachable using IPv6 by the end of 2021. In other words, all their public mail and web servers will have to support IPv6 connections within the next two years. The various government entities and their suppliers have made a joint statement of intent to that effect. Earlier this month, a further group of suppliers signed up to the plan.

Implementation of existing standards would make the internet much more secure New boost for IPv6 implementation in the Netherlands

The statement of intent is an initiative by Logius, the Forum for Standardisation and VNG Realisatie, intended to expedite IPv6 adoption. The Forum's Bart Knubben had previously indicated that suppliers needed to improve their tools and services. "It's important that software suppliers and service providers make the standards easy to implement, or -- even better -- make support for the standards the default position." He believes that both government organisations and their major service providers should be individually urged to take action.

Exchange meetings

Government organisations, suppliers and service providers have since agreed to do all they can to support IPv6, so that government servers can be IPv6-enabled in good time. Signatories to the statement of intent are also calling on the Forum for Standardisation to draw up a Joint Ambition Statement for IPv6, following the model adopted to promote the internet security standards TLS/HTTPS, DNSSEC, SPF/DKIM/DMARC, HSTS and STARTTLS/DANE. The approach would involve periodic progress testing and reporting. Last month, the various parties held three meetings, at which municipal authorities presented their IPv6 cases. Experiences and plans were also exchanged and stumbling blocks identified. The meetings additionally laid the foundations for the Joint Ambition Statement.
