What is this IP/DNS tool used for?

These tools help you look up IP addresses, perform DNS lookups, check domain WHOIS information, test SSL certificates, and diagnose network connectivity issues.

Is my IP address visible to you?

No. When you use our What Is My IP or IP lookup tools, the IP lookup is performed entirely from your browser using public APIs. We do not log or store any IP addresses.

How does the SSL checker work?

Our SSL checker attempts to connect to the specified server and retrieves its SSL/TLS certificate details, including issuer, validity period, and supported protocols. This helps you verify certificate health.

Can I test my website status?

Yes, use the Website Status Checker to ping any URL and verify if it is online. The tool reports HTTP status codes and response times.
