This tool detects whether your IP address is an IPv6 address. If your ISP supports IPv6, the connection will prefer IPv6, and we will confirm your connection to this webpage using an IPv6 address.

If an IPv6 address is detected, you can perform an IPv6 ping test to verify that incoming connections work correctly.

Note: The IPv6 ping test may fail if your firewall blocks ICMPv6 traffic. While an IPv6 firewall is advisable, allowing ICMPv6 is recommended for network diagnostics and proper IPv6 functionality.
