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The details registered about me/my company are incorrect or out of date.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.
We've previously provided a handy checklist to help you draw up a Cyber Incident Response Plan. Such a plan will be invaluable if your security is ever compromised. But there's more to good incident response than having a good plan. Ideally, you should go through the following five phases. We recommend including them in your plan.
Preparation is vital. Put together a team that can swing into action if there's a cyber incident, and formulate a Cyber Incident Response Plan. You also need to train the team, define response processes and make sure that they're firmly embedded.
Phase 2: Identification and analysis
The second phase of a good response involves detecting the incident and sounding the alarm. At that point, it's important to gather any information that can shed light on the situation. What happened and when? Who gained access to what? Are event logs available? In some cases, such information can be used as evidence, so it's important to make sure everything is properly recorded.
Phase 3: Mitigation and resolution
Once you become aware that there's been an incident, you need to act quickly to limit and repair the damage. What that entails depends on the type of incident. If you've been hacked, for example, you may need to remove the hackers' malicious software. But if you've had a data leak, the emphasis will be on closing the relevant systems and reporting the event to the Data Protection Authority.
Phase 4: Restoration and testing
Following an incident, you'll need to restore the affected systems. They should be tested thoroughly before being released for use. Are there any signs of abnormal behaviour or anomalies in the data? Make sure your Incident Response Plan says how long the systems will require extra monitoring.
Phase 5: Evaluation
Once the dust has settled, the team should evaluate the incident and the response. Were all problems resolved? What didn't go well and could be improved in future? Update your plan in line with the conclusions.
Good luck producing your plan!
