Description

Hello team and @angristan ,

I have a Ubuntu 20.04 VPS on AWS Lightsail and I installed wireguard. IPv6 is supported and I can ping IPv6 address. When I access some websites like google.com or youtube.com, IPv4 is preferred by default and I have to pass capthca screen sometimes for security reasons. Some shared public IPv4 address on cloud are blacklisted or suspicious because they are used too much on the cloud.

To overcome this issue I would like to use IPv6 by default and IPv4 as a fallback.

You can see the test results on https://ipv6-test.com/

Thanks

Contributor guide

Research direction
Examine the WireGuard install script to locate where DNS and default routing are configured. Modify the configuration to prefer IPv6 by setting appropriate DNS servers (e.g., Google's IPv6) and adjusting the AllowedIPs or routing table to favor IPv6.
