WHOIS Lookup
See which registrar a domain is with, when it expires and which nameservers it uses.
Analysis messages from the checker are currently in Dutch.
How does it work?
WHOIS data shows who manages a domain and until when it is registered. Many registrars shield personal data.
Frequently asked questions
Why do I not see an owner?
Registrars shield personal data (GDPR). You mainly see registrar, dates and nameservers.
Why does the expiry date matter?
An expired domain means website and email stop working. Turn on auto-renewal.
Does this work for all extensions?
For most, but some registries limit WHOIS queries.
