What is my IP address?
Your public IP address and the country websites see for you right now. Check in two clicks whether your VPN really changes it. Nothing is stored.
Open the toolWebRTC leak test
Check in your browser whether WebRTC reveals a different IP address than your VPN shows. Test without the VPN, then with it: your address should not return.
Open the toolDNS leak test
See which DNS resolver answers your lookups. Test without the VPN, then with it: if the same provider shows up again, your DNS requests leak.

How to use them together
Open the IP address check without your VPN, turn the VPN on and check again: the address should change. Then run the WebRTC leak test, which shows whether your browser still reveals your own address by another route. Finally run the DNS leak test, which shows whether your DNS lookups still go to your internet provider.
