DNS Connectivity Test

What Does This Tool Do?

The DNS Connectivity Test probes public DNS infrastructure — Cloudflare trace, Google DNS-over-HTTPS, Cloudflare DoH, and an IP echo check — to confirm your network can resolve domains and reach major resolvers. It reports latency and flags IP mismatches between providers.

Use it to diagnose slow browsing, failed API calls, or suspected DNS routing issues when working through VPNs or corporate networks. This complements but does not replace dedicated DNS leak test sites.

Frequently Asked Questions

What does this DNS test check?

Whether your browser can reach Cloudflare and Google DNS endpoints and resolve test queries.

Is this a DNS leak test?

Partially. It detects connectivity and IP mismatches but does not enumerate all system resolvers like dnsleaktest.com.

Why do probes time out?

Google/Cloudflare DNS may be blocked on some networks. Timeouts are reported instead of hanging.

What should I do if all probes fail?

Check VPN settings, try a different exit node, or verify firewall rules allow HTTPS to public DNS services.
