Network & Internet Tools

Diagnose connectivity and domains with speed tests, IP lookup and geolocation, ping, traceroute, port checks, DNS and reverse DNS, MX/TXT/SPF/DKIM/DMARC record checks, DNS propagation, WHOIS, domain age, SSL certificate inspection, HTTP headers, website uptime, and CDN detection. Run the check that matches your question, then read the result in context of what a browser-based probe can and cannot see.

Interpreting results

Speed and latency reflect the path from your browser to the test target, not a guarantee for every user. DNS and mail-record tools show what public resolvers return at query time. SSL and header checks describe the certificate and response metadata the tool retrieved.

Browser-check limits

Firewalls, VPNs, corporate proxies, and CDN edge routing can make your view differ from another network. These tools do not replace hosting-panel diagnostics or ISP-side traces. Port and ping reachability may be blocked by the remote host even when the service is healthy for other clients.
