What is the best reference document for a Translator that facilitates:

- IPv4only - to - IPv6only, and
- IPv6only - to - IPv4Only 
clients message exchanges? 

Is this communication bidirectional or works only from IPv6only-to-IPv4only client (meaning IPv6only client has to initiate the communication)?

How can Translator or DNS64 tell IPv6 only client the IP of IPv4 only client, and vice versa?

Thanks,
Dusan.
