Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to check if your VM is using an IPv6 for outbound connection or not.
It could be possible that the site you were using to detect IP was not capable of detecting IPv6.
The best way to check this is to,
- Open CMD as admin
- curl -4 https://ifconfig.me
- curl -6 https://ifconfig.me
- or Use a browser and access "https://ifconfig.me"
Kindly let us know if this helps or you need further assistance on this issue.
Thanks,
Kapil
