IP, DNS and WebRTC: what a result can tell you

An IP address shown by one website describes one observed connection, not your entire device.

IP, DNS and WebRTC: what a result can tell you
Methodology & limitations

This is a decision and testing guide, not a guarantee of anonymity, access to any particular service or protection against every threat. Keep your operating system updated, use unique passwords and enable multi-factor authentication where available.

What it offers

An IP address shown by one website describes one observed connection, not your entire device. DNS and WebRTC checks examine different behavior. Record a baseline without the VPN and repeat with it enabled, using the same browser and network. A reverse proxy can also change the address seen by a site. Do not treat one green indicator as proof of complete protection.

A practical checklist

  1. Record your operating system and app version.
  2. Save the official policy and plan you relied on.
  3. Change one setting at a time and repeat the test.
  4. Note the date, network, result and unresolved questions.

Before you subscribe

Check the exact app, operating-system version and subscription tier. Test the functions you need on your own connection before committing to a long subscription. A website description is not a measurement of reliability or speed.
