How to receive IPv6 traffic to a server located in an IPv4 network?

Question

Domain Name System

Situation: Apple rejects our app in the AppStore because it only uses IPv4 to communicate with our backend and does not support IPv6.
The backend is located on an IPv4 network (Microsoft Azure), and we use Route53 (AWS) for the DNS service.

How can we serve IPv6 clients from our server?

Answer 1

How can you maintain the bricks in the juicer???
It doesn’t bother you that these are fundamentally different networks, and the traffic of some is routed to IPv4 and others to IPv6, and all you need for this is to at least raise IPv6 traffic on the interface and register it in DNS, all the services you named have been able to do this for a long time . Your task is only to request them from the relevant providers and set them up.

Answer 3

Get hosted on an IPv6 network and use a proxy or 6-to-4 tunnel. For example, in 3proxy for port forwarding
tcppm -iIP_v6_address port IPv4_backend_address port
