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The details registered about me/my company are incorrect or out of date.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

Always a popular means of communication, e-mail is especially important while so many people are working from home. However, the e-mail protocol has a number of vulnerabilities. That's a particular worry in the business world, where security is a high priority. Fortunately, the vulnerabilities can be addressed by implementing modern e-mail standards. Using the standards can help prevent issues such as phishing, malware and spoofing.
However, implementing e-mail standards correctly and ensuring that they actually increase security is far from easy. There's plenty of information on the internet, but where do you begin? We've developed this handy checklist to help.
For .nl registrars, we've developed a comprehensive e-learning module on e-mail standards. Available now at our SIDN Academy, the module explains everything you need to know about implementing e-mail security standards. Forgotten your login details? Drop a line to support@sidn.nl.
