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  • The details registered about me/my company are incorrect or out of date.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

ISC publishes ten webinars on BIND and DNSSEC

And our hands-on articles will help you get going

  • Thursday 30 April 2020

A useful series of ten webinars about BIND and DNSSEC has been published by ISC, the developer of BIND DNS software. About one a week has been put up for the last couple of months, and all ten are now available on YouTube. Each webinar lasts about an hour and consists of visuals (text and diagrams) with an explanatory voiceover by Alan Clegg, until recently System Engineer at ISC.

The ten webinars are:

  1. Why Do We Need DNSSEC?

  2. DNSSEC Development & Deployment (History)

  3. Cryptography and DNS Background for DNSSEC

  4. DNSSEC Resolution and Validation

  5. DNSSEC Record Types, Keys, Signatures, and NSEC

  6. DNSSEC Record Types, Keys, Signatures, and NSEC, Part 2

  7. DNSSEC Signing with BIND

  8. Key Rollover and Algorithm Rollover

  9. Key Maintenance With the New KASP Tool

  10. DNSSEC Troubleshooting

Episode 1 of ISC's webinar series on DNSSEC.

Getting down to work

Want to get cracking with your own DNSSEC implementation? You may also find it helpful to read our two earlier articles giving hands-on advice about BIND-based implementation:

Since the release of version 9.16, the latest Extended Support Version (ESV), BIND now features 'DNSSEC policy' functionality. From (development) version 9.15.6, policies for key management and zone signing can be included in the named.conf configuration file. The software will then automatically ensure that signatures (RRSIG records) and ZSK/KSK pairs are always up-to-date. As a result, scripts and cron jobs are no longer necessary to keep signed zones updated. For more information about the KASP Policy, see this article. We'll shortly be updating our hands-on article to cover the new functionality.

Infoblox, PowerDNS and Unbound

We can also help with the implementation of DNSSEC using other DNS software (i.e. not BIND). Go to our DNSSEC section for hands-on articles that explain how to implement signing and validation using Infoblox, PowerDNS and Unbound. A comprehensive overview of the various DNS software packages is provided in this article.
