FAQ

Frequently asked questions

WHOIS is a protocol that allows you to look up domain registration information: registrar, creation and expiry dates, DNS servers and status. This information is public and accessible via port 43 (RFC 3912).

Yes, 100% free with no signup. You get a complete report with WHOIS, SSL and DNS data. No credit card, no commitment.

Our tool connects to the server on port 443 and analyzes the TLS certificate: issuer, validity dates, protocol used (TLS 1.2, 1.3), cipher and SAN domains. A colored badge instantly indicates the certificate status.

The tool resolves A (IPv4), AAAA (IPv6), MX (email), NS (DNS servers), TXT (SPF, DKIM, etc.), CAA (certificate authority) and SOA (Start of Authority) records. Each type is displayed in a dedicated table.

A misconfigured domain can lead to security issues (expired certificate), email deliverability problems (incorrect MX/SPF records) or availability issues (misconfigured DNS). Regular checks help prevent these incidents.
