IPv4 and IPv6: how to read your connection result
The IPv4 or IPv6 label describes the connection used for the current request. It does not establish whether every application on your device can use both protocols.
How can you recognize IPv6?
An IPv6 address has 128 bits. Its text representation uses hexadecimal groups separated by colons; a double colon can compress a run of zero groups.
Why is only one address shown?
This tool reports the source address of one HTTP request. A request arriving over IPv4 cannot, by itself, tell the server your IPv6 address.
How should you interpret the result?
Record the address and connection type, then compare the result after a network change. For address scope, see public and private IPs. Return to the connection panel to refresh the measurement.
