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  • The details registered about me/my company are incorrect or out of date.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

Internet of Things: opportunities, problems and solutions

Interactive Dutch-language webinar

smart city

You are warmly invited to take part in our Dutch-language webinar 'Internet of Things: opportunities, problems and solutions', from 3 to 4pm (Dutch time) on Thursday 3 September.

The Internet of Things (IoT) is an increasingly visible part of everyday life. We already take smart lights, TVs and thermostats almost for granted. And a growing number of household appliances, including washing machines, cameras, robot vacuum cleaners and energy meters, now operate via (wireless) network connections. Outside the home, the IoT plays an ever more significant role in the fabric of the modern world, enabling smart power grids, intelligent transport systems and the like.

Downside of the IoT

Unfortunately, the IoT's rise has a downside. Some smart appliances, particularly consumer appliances, bring security risks. A smart lock that opens your front door as you approach is a liability, for example, if its digital security isn't up to scratch. Then there are IoT gadgets that report personal information to their manufacturers, or even leak it to the world. And who is actually operating the manufacturer's (cloud-based) infrastructure? Problems can also arise if IoT devices are recruited into botnets, which can then be used to launch DDoS attacks.

Possible solutions

The current situation could be improved in various ways. Possible approaches include:

  • Regulation and certification to ensure that manufacturers secure their products properly and provide security updates

  • Active intervention by internet service providers (ISPs) in response to abuse reports, such as quarantining domestic customers identified as sources of DDoS traffic

  • Active scanning of network traffic, e.g. by dedicated devices or by software installed on routers

Webinar

Our Dutch-language webinar will explore the context of the issues posed by the IoT and the various possible solution pathways. We'll also talk you through the challenges associated with scanning and analysing network traffic. The webinar will be chaired by Cristian Hesselman, Director of SIDN Labs.

Speakers

  • Jelte Jansen Jelte's main focus is the study and advancement of new technologies. He develops prototypes, such as the prototype for Security and Privacy for In-home Networks (SPIN).

  • Elmer Lastdrager Elmer has a keen interest in security and privacy on the Internet of Things. He does empirical and other research in the field of Usable Security with a view to identifying ways of making home networks more secure.

Questions welcome!

The webinar will be interactive: you'll be able to ask questions at any time using the chat facility. Questions will be answered live during the webinar wherever possible.
