IPV6 testing for embedded devices

I would like to test the IPV6 stack on an embedded system. How can I do that ? Would establishing a test link between this device and another PC be a "good enough" test ?

I was thinking about using a tool like socat to establish the link.

Should I ask this here or on stackoverflow ?

• Depends on the reason for performing the test. If you want to know whether the device can provide a certain function, you should test whether that function actually works. If the function is "can establish IPv6 TCP connections", then this is what you should test - connecting to a PC would then be good enough.

  If you want to certify IPv6 support for the device, this test certainly wouldn't be sufficient. There are feature lists for IPv6 tests that are used in certification, e.g. the IPv6 Ready Logo.
