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  • The details registered about me/my company are incorrect or out of date.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

Sharetrada: A knowledge-sharing site for (future) ENTRADA users

Join Sharetrada, a site to share, discover and discuss the capabilities of your DNS storage and analysis platform ENTRADA.

Last month, my colleague Maarten and I had the pleasure of attending the first Swiss Security Tools Hackathon organised by the Swiss CERT and the SWITCH registry in Zurich.

The goal of the hackathon was to develop tools and improve existing solutions to make the life of internet security professionals a little easier and the internet a safer place for its users.

Connecting the ENTRADA community

One of the main topics was ENTRADA, our open-source platform for network data analytics. We and other registries use ENTRADA to improve insight into DNS traffic. DNS data analysis has many useful applications. It enables us to detect malicious DNS activities – e.g. fraudulent domain names and botnets – for example. We can also measure the adoption of new DNS extensions and improve our understanding of recursive resolver behaviour as a starting point for improving services.

Sharetrada is a knowledge-sharing site where ENTRADA users can share and discuss their ENTRADA queries. We've created it to foster knowledge exchange amongst ENTRADA users and to give people who are interested in ENTRADA a better insight into the platform's capabilities.

On Sharetrada, users can post queries in different categories, ranging from DNSSEC, to Resolver Behaviour and Security. Only registered users can see and post Security queries. But anyone's free to suggest ways we might improve Sharetrada or post general questions in the Q&A section.

The Sharetrada homepage

Already we've seen users sharing advice on extracting metrics such as DKIM usage, query rates and the percentage of potentially validating resolvers from an ENTRADA cluster. And more posts are going up all the time!

What else happened at the hackathon?

Sharetrada wasn't the only ENTRADA-related project to feature at the hackathon. Participants developed an anomaly detection system for DNS queries, made it possible to import dnstap logs directly into ENTRADA and added support for new DNS protocol fields. In a non-ENTRADA-related project, participants developed a complex bot for IntelMQ to collect and process security feeds.

Thanks to Michael Hausding and SWITCH for hosting such a great event.

And, if you like the sound of the Sharetrada community, why not register today?
