IPv6leaktest

IPv6leaktest is a website that allows users to check for IPv6 DNS leaks. An IPv6 DNS leak occurs when a user's computer or device uses an IPv6 DNS server that is not provided by their VPN service, even when connected to a VPN. This can reveal the user's real IP address and location to the websites they visit, defeating the purpose of using a VPN for privacy.

The IPv6leaktest website works by asking the user's browser to make DNS requests. If the user has an IPv6 leak, these requests will be routed through their regular ISP's DNS servers instead of the VPN's DNS servers. The website then analyzes the results to determine if an IPv6 leak is present. It displays the IP address that was used for the DNS resolution, allowing users to see if it matches their VPN's IP address or their actual ISP-assigned IP address.

If an IPv6 leak is detected, users are advised to take steps to prevent it. Common solutions include disabling IPv6 on their network adapter, configuring their VPN client to use specific DNS servers, or using a VPN service that explicitly offers IPv6 leak protection. The website often provides links to guides and resources that explain how to perform these troubleshooting steps on different operating systems. Regular testing is recommended for users who rely on VPNs for privacy and security.
