Multi-target ping lets you test multiple hosts at once. • Speed Test — Measure real-world download and upload speeds via Cloudflare's global network. • Traceroute — Trace the full path your data takes across the internet, hop by hop. • DNS Lookup — Query A, AAAA, MX, CNAME, TXT, and other DNS record types for any domain. • Port Scanner — Scan common or custom port ranges to check what's open on any host. • IP Geolocation — Look up the geographic location, ISP, and network info for any IP address. • WiFi Info — See your current network name, IP address, and connection details at a glance.

SCAN HISTORY Every scan is automatically saved so you can compare results over time, share diagnostics, and track network behavior.
