Vulnerability, Opera 16.12 on Linux Mint 17.3 Rosa

[CDU_und_SPD_Nein_danke 0]

Hello everybody!

I use Opera 16.12 on Linux Mint 17.3 Rosa.
Now I have even made a IP check.
Most sites show me the AirVPN address of each country.
On this page and some other pages, my IP6 address appears.

Page: heise.de/netze/tools/meine-ip-adresse/

I have checked my router This IP6 address and is identical to the IP6 address of the router.
It does not matter if I have enabled in Opera JavaScribt or not.
Connected I'm with the AirVPN.

If you visit with Firefox these pages that IP6 address will not be displayed.
How is that possible?

Thank you very much

You should completely disable IPv6 when you use VPN.

Maybe the IPv6 support is disabled in your Firefox, but in any case disable it system wide.

Hello !

 

I think you have to turn off IPv6 completely.

 

Have you stopped WebRTC from leaking? You can use ipleak.net

 

You probably already know. But it's good to mention
