The Internet currently uses two address families: IPv4 and IPv6. IPv4 is increasingly scarce, while IPv6 is a much larger address space. That is, we have run out of IPv4 addresses, while we have nearly infinite IPv6 addresses.
When you visit this site, your browser connects using either IPv4 or IPv6 for each request. Many networks support both (dual-stack), but some support only one.
The IPv4 and IPv6 tests above work by loading small resources from IPv4-only and IPv6-only hostnames. A successful test means your network can reach that address family. A failure usually indicates that the address family is unavailable or blocked on your network.
A failed IPv6 test does not necessarily mean something is broken on your device or network. Likewise, IPv6 connectivity does not necessarily imply better or worse network performance.
