How it works

Every test runs locally with hardened DNS-over-HTTPS lookups.

  1. IPv4 coverage
    Queries DNS A records to confirm IPv4 reachability.
  2. IPv6 readiness
    Performs AAAA lookups to surface IPv6 endpoints.
  3. Secure transport
    Uses Google DNS-over-HTTPS to keep lookups private.
  4. Latency check
    Measures response times from our global edge network to verify connectivity.
  5. Browser-native
    DNS lookups run in your browser. Latency tests are proxied securely.
