Get your network
unstuck.

Start with your connection. Then check where a domain points and whether its certificate can be trusted.

01 / Your connection

Your public IP address

216.73.216.236

The address this website sees for this request.

Refresh address ↻

A VPN, proxy or shared router can change this address. This is not your device’s local Wi-Fi address and does not identify a person. We show the connection received by our server, not untrusted forwarded headers.

02 / Domain routing

DNS checker

See the public records behind a domain: web addresses, mail routing, verification records and more.

For TXT checks, names such as _dmarc.example.com are supported.

One Google Public DNS resolver view—not a worldwide propagation test. TTL is the remaining cache lifetime in seconds; results can differ by resolver.

03 / Secure connection

SSL certificate checker

Check certificate trust, hostname, issuer and expiration for a public HTTPS website.

Enter the exact hostname, including www if needed. HTTPS port 443 only.

One TLS connection, no page download. This is a certificate check, not a security grade or comprehensive vulnerability scan.
