Ignoring the discussion about IPv6 adoption (or lack thereof) and answering
the question about coexistence;

NAT64 frequently coupled with DNS64 is the primary mechanism for
coexistence between IPv4 and IPv6, see the following as a starting point;

RFC6144 - Framework for IPv4/IPv6 Translation
RFC6146 - Stateful NAT64: Network Address and Protocol Translation from
IPv6 Clients to IPv4 Servers
RFC7755 - SIIT-DC: Stateless IP/ICMP Translation for IPv6 Data Center
Environments - for IPv4 Client to IPv6 Servers

Hope this helps.
