From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Need help with NetworkManager, VPN and IPv6 (lemm.ee)

submitted 2 months ago by [email protected] to c/[email protected]

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)

Huh, I misremembered then. I stand corrected.

Notable though that there are specific countries (such as India) where adoption is far higher at 72%

Dunno why my comment was removed but I remarked that it's either fed to them as scraps or it's in use by scammers and bots.
