Tests download, upload, latency, jitter, loaded latency, and packet loss — then gives you a Bufferbloat Grade (A–F) showing how your connection performs under real load. Powered by Cloudflare. * Ping Ping any host with a single burst or continuous mode. Watch latency in real time on a live scrolling graph with color-coded results and timeout detection. * Traceroute Trace the full path to any host with live reverse DNS lookups showing real router and infrastructure hostnames at every hop. * DNS Lookup Query A, AAAA, MX, TXT, CNAME, and NS records for any domain. * DNS Propagation Check if your domain has propagated across 10 major DNS servers worldwide including Google, Cloudflare, Quad9, and AdGuard. * DNS over HTTPS (DoH) Test whether your device is using encrypted DNS.
