Network Tools
Network Tools on DeviceHub cover the full suite for path and privacy triage: IP Address and IPv6 Test for public egress and dual-stack echoes, best-effort DNS Privacy Check and WebRTC Leak Test for VPN path consistency, Port Checker and HTTPS Reachability Check for Cloudflare-edge TCP/HTTPS reachability, HTTP Headers for sanitized request echoes, and Connection Information for Network Information API hints. Lookups may use DeviceHub Cloudflare APIs and documented public echoes; edge probes are not LAN scanners.
Start with IP Address, WebRTC Leak Test, Connection Information, or IPv6 Test for everyday checks, then drill into DNS privacy hints, port/HTTPS edge probes, or header echoes when a symptom needs a sharper lens. Results stay honest about limits, third-party echoes when fallbacks run, best-effort DNS without an authoritative DeviceHub resolver logger, WebRTC candidates shown on-screen, and Safari gaps for Network Information.
