Sorry I should have explained the rationale for this in my initial message. For privacy conscious individuals one tool for improving online privacy is a VPN service. Many VPN service providers recommend disabling ipv6. This is because of ipv6 leaks. https://ipv6leak.com/ is a ipv6 leak testing site. It is the first result when searching for "ipv6 leak" with searx.ir. Using this website I can see that the privacy provided by my VPN service provider is compromised by an ipv6 leak when I enable ipv6. This is why I have ipv6 disabled. I am open to suggestions on free software alternatives to using a VPN service that do not require ipv6 to be disabled. The current VPN service I am using allows the use of a openvpn client so I do not need to install any proprietary software on my computer to use their service. I am aware of Tor or I2P but have not yet looked into how I could to send my network traffic over those networks.
