Complete domain intelligence: WHOIS registration, DNS records, and SSL certificate details.
What does this domain data mean?
WhoisJSON turns WHOIS, DNS, and SSL records into practical answers: registration status, renewal risk, email security posture, EPP restrictions, and monitoring actions.
Domain registration is valid for 252 more days
The expiration window does not look urgent based on the current WHOIS/RDAP data.
SSL certificate is valid
The domain currently presents a valid TLS certificate.
Email is configured, but no DMARC record was found
MX records indicate the domain can receive email. Without DMARC, spoofing protection and reporting are weaker.

When does tonnesen.dk expire?
tonnesen.dk expires in about 252 days, based on the current WHOIS/RDAP expiration date.

Yes. MX records are present, so the domain is configured to receive email.
Is tonnesen.dk protected against email spoofing?

Understand Any Domain in Seconds
Each domain page on WhoisJSON combines three data sources in one view: WHOIS registration data (registrar, creation/expiry dates, status), DNS records (A, MX, NS, TXT, SOA), and SSL certificate details (issuer, validity, encryption). Need this data programmatically? All three endpoints are available through a single API key — 1,000 free requests/month.
Stay Informed with Domain Monitoring
Don't just check once — monitor domains continuously. Get email alerts when WHOIS ownership changes, DNS records update, SSL certificates expire, or a domain becomes available for registration. Monitoring is included in every WhoisJSON plan.
