How do I fix a DNS leak?

Configure your VPN to use its own DNS servers. Most reputable VPN apps have a "prevent DNS leak" setting.

How do I disable WebRTC to prevent leaks?

In Firefox, set media.peerconnection.enabled to false in about:config. In Chrome, use uBlock Origin with WebRTC blocking.

Does my VPN support IPv6?

Many VPNs still do not tunnel IPv6. Disable IPv6 at the OS level or choose a VPN with IPv6 leak protection.

Should I test every time I connect?

Yes, at least initially. VPN configurations can change and updates may re-enable leaky protocols.
