Tool guide

Clear input, result, and evidence boundaries

Compare observed IPv4 and IPv6 egress paths and distinguish no IPv6, probe failure, and baseline mismatch.

01

Input and method

No required input; an expected IPv6 address or ASN is optional.

02

Reading the result

Observed v4/v6 addresses, ASN, availability, vantage, and comparison status remain separate.

03

Boundary and privacy

No IPv6 and a failed IPv6 probe are different states; a leak conclusion requires a user-supplied baseline.

FAQ

Frequently asked questions

What does IPv6 Leak Test check?

Compare observed IPv4 and IPv6 egress paths and distinguish no IPv6, probe failure, and baseline mismatch.

What input does IPv6 Leak Test accept?

No required input; an expected IPv6 address or ASN is optional.

How should I interpret IPv6 Leak Test results?

Observed v4/v6 addresses, ASN, availability, vantage, and comparison status remain separate.

What can IPv6 Leak Test not prove?

No IPv6 and a failed IPv6 probe are different states; a leak conclusion requires a user-supplied baseline.

How does IPv6 Leak Test handle input and results?

Input is used only for this explicit check. No IPv6 and a failed IPv6 probe are different states; a leak conclusion requires a user-supplied baseline.

When should I run IPv6 Leak Test again?

Run it again after the relevant network, address, browser environment, or target changes. Observed v4/v6 addresses, ASN, availability, vantage, and comparison status remain separate.
