I would still be interested to understand how DCC works in the following scenarios:
a. IPv6 and IPv6 - non-passive and passive.
b. IPv6 and IPv4 - in both directions and non-passive / passive.
c. Situations where one or both ends have bit IPv6 and IPv4 connectivity - both non-passive and passive.
You will need to research this as I am not aware of anyone having looked into it.
