Network & privacy guides

Understand the network, then verify your own connection with practical tools.

IP fundamentals

Understand public and private IPs, shared exits, and address changes, then check your current network and VPN connection step by step.

Learn about IPv4 and IPv6 address formats, dual-stack connections, and VPN routing, including why one device can use different exits.

Understand IP databases, registration, routing, and physical usage locations, and learn to compare conflicting geolocation results.

Learn what a public IP lookup reveals and how shared addresses, VPNs, and browser signals affect identification and privacy.

Understand VPN databases, hosting networks, proxy activity, and source disagreements. Separate address detection from risk and connection leaks.

Compare VPN and proxy traffic coverage, exit addresses, and configuration, then verify the result with IP, DNS, WebRTC, and fingerprint tests.

Learn how device, Canvas, WebGL, language, and time-zone signals combine, and what a local fingerprint summary can and cannot establish.

Compare a baseline and VPN connection to understand STUN candidates, dual-stack paths, mDNS, and tests that cannot complete.
