IPv6 connectivity test

IPv6 and why it exists

The original Internet Protocol, IPv4, provides about 4.3 billion addresses — a number that seemed enormous in the 1980s but ran out as billions of phones, computers, and smart devices came online. IPv6 is its successor, offering a practically unlimited pool of addresses and improvements in routing efficiency.

This page checks whether your connection can reach the internet over IPv6 and shows which protocol you used to load this site. Many networks now run both protocols side by side, a setup called dual-stack.

What the result means

If IPv6 works, your connection is ready for the modern internet and future-proofed as IPv4 addresses become scarcer. If you are IPv4-only, everything still functions normally today, but enabling IPv6 — often a simple router or ISP setting — can improve connectivity to newer services.
