What is IPv6?
IPv6 (Internet Protocol version 6) is the newest version of the Internet Protocol. It provides a much larger address space than IPv4, supporting virtually unlimited devices online.
How do I know if I have IPv6?
This tool automatically detects it. If the IPv6 card shows a green checkmark and an address starting with 2xxx:, you have IPv6 support.
Why is IPv6 important?
IPv4 addresses are running out. IPv6 ensures the internet can continue growing. It also offers better routing, security, and can provide faster connections.
What does the readiness score mean?
The score (0-10) measures how well your connection supports IPv6. A score of 8-10 means excellent support. Below 5 means your ISP has limited IPv6.
What is a WebRTC leak?
WebRTC is a browser technology for real-time communication. It can accidentally expose your real IP address even when using a VPN. Our test detects this.
Is my data stored?
No. All tests run in your browser. IP addresses are not logged, stored, or tracked. The tool is completely private.
