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  • The details registered about me/my company are incorrect or out of date.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

The 2022 Passive and Active Measurement Conference (PAM2022) is about to start. SIDN Labs is proudly hosting this virtual conference, the seventeenth edition of which takes place this year. If you haven't registered yet, please hurry! Registration is free.

Well-established academic conference on internet measurements

The Passive and Active Measurement Conference is a well-established academic conference on internet measurements. SIDN Labs is proudly hosting the seventeenth edition, which will take place on 28 to 30 March 28 2022, on Zoom. PAM brings together researchers and operators to discuss novel and emerging work in network measurement and analysis.

Being a peer-reviewed conference, it has a Technical Programme Committee (TPC), which oversaw evaluation of the submitted papers and chose the top ones for publication. The TPC Chairs, Cristel Pelsser and Oliver Hohlfeld, worked with the TPC members and were able to choose thirty papers for PAM2022 out of the 62 that were submitted (48% acceptance rate).

The accepted papers are distributed across twelve technical sessions, covering topics such as DNS, DDoS, RPKI, Routing, BGP, peering, video conferencing and other topics.

We invite you to check the conference programme for details.

Keynote speeches from two renowned scientists

PAM2022 will also feature two keynote speeches. The first one will be given by Dr Johanna Amann from the International Computer Science Institute (ICSI). Her keynote entitled “Expect the unexpected: Lessons from a decade of passive network measurements” will cover the results of analysis of a decade's passive SSL/TLS measurements.

The second keynote will be by Dr Les Deutsch, from NASA's Jet Propulsion Laboratory (JPL). His keynote, entitled “The Deep Space Network: Connecting the Solar System”, will cover NASA's older-than-the-internet interplanetary communications network, which is used by all satellites (such as Hubble and James Webb) as well as probes (such as Voyager).

Excited and proud to host PAM2022

We are both excited and proud to be hosting PAM2022. As the operator of the Netherlands’ top-level domain (.nl), internet measurements are key to SIDN’s operations and so a conference like PAM is important to further strengthen the measurement community and to further advance our own knowledge in this space.

Also, we are heavily involved in network measurement research ourselves at SIDN Labs, which is part of SIDN’s mission to help further the security of the internet and contribute back to the community through our measurement papers and open-source tools.

Big thank you

Obviously, we are extremely grateful to everyone who is helping us to make the event happen. Without your help, PAM2022 could not take place. Thanks to all the organising committee.

Please don't forget to register! ,Just go to https://pam2022.nl. We hope you enjoy PAM2022!

We wish everyone a great conference! See you online.
