* Speed Test
Measures your connection the way it should be measured. 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. Checks 6 major DoH providers and estimates your protection level.

* Port Checker
Scan common ports on any host to see what's open or closed.

* WHOIS
Look up domain registration and ownership details instantly.

* SSL Inspector
Inspect SSL/TLS certificates — view issuer, validity dates, and days until expiry.

* WiFi Info
See your local IP, external IP, subnet, gateway, and DNS. Enable location permission to reveal signal strength in dBm, SSID, BSSID, and channel with 2.4/5 GHz detection.

* IP Info
Geolocate any IP address with a map view, ISP, timezone, region, and coordinates.
