What Is a VPN—and What Does It Actually Protect?
A VPN encrypts your traffic to its own server and gives you that server's exit address — but it's a narrower protection than the marketing suggests, and worth understanding precisely.
Practical VPN guides covering tunnels, detection, exit reputation, DNS, WebRTC, IPv6, and privacy testing.
A VPN encrypts your traffic to its own server and gives you that server's exit address — but it's a narrower protection than the marketing suggests, and worth understanding precisely.
A VPN's tunnel-setup, encryption, and DNS handling happen in a specific order — understanding each step clarifies what's actually protected and where a misconfiguration can leave a gap.
VPN detection is a confidence judgment built from multiple observable signals — known exit-node lists, hosting-range registration, and behavioral patterns — not a single definitive flag.
Residential and datacenter VPN exits differ in source network, capacity, consistency and cost — and each carries a different classification profile as a result.
Websites block VPN traffic for licensing compliance, fraud prevention, abuse control, and regional-rules reasons — rarely as a blanket anti-privacy stance.
A location mismatch between your IP, DNS resolver, and browser settings has a handful of common, checkable causes — worth working through in order rather than guessing.
A five-minute check across public IP, DNS, WebRTC, and IPv6 turns a vague worry into a clear answer about whether your VPN is actually protecting what you think it is.
