I was setting up my laptop for traveling and adding Wireguard VPN configuration.

The Wireguard config generated by router only contains IPv4 address (10.0.5.x), and while testing the VPN to my surprise “what is my ip” websites can find my IPv6 address (I USB tethered mobile connection to my laptop).

It looks like NetworkManager does nothing about IPv6 connection if VPN doesn’t have IPv6 settings, which is bad for road warrior type of VPN configuration.

Is there an easy toggle to turn of IPv6 if VPN is connected and otherwise? Or is only option to disable all IPv6 no matter what?

    Or you could just… learn to use the modern internet that 60% of internet traffic uses? Not everyone has a dedicated IPv4 anymore, we are in the days of mobile networks and CGNAT. IPv4 exhaustion is here today.

    Where are you getting 60%? Google’s IPv6 Adoption page has it under 50% still:

    Screenshot of Google saying "IPv6 Adoption / We are continuously measuring the availability of IPv6 connectivity among Google users. The graph shows the percentage of users that access Google over IPv6." with a graph climbing from near 0% in 2008 to 45% in September 2024

    (while other stats pages from big CDNs show even less)
