Trying to use an IPv6 only machine runs into a roadblock when you need to access a legacy IPv4 resource.
The best solution would be to convince services to move to an IPv6 first solution, incrementally adding reverse proxies for existing services and deploying new services to IPv6 only, with an IPv4 gateway only as needed.
Deploying new services to IPv6 only is much simpler than dual-stack, as you only need to worry about one set of configuration, firewalls, etc. Adding an IPv4 proxy on top, for legacy support, is then a simple, and contained, extension.
However, until that happens you still need a solution.
I found setting up DNS64 + NAT64 for my IPv6 only machines was pretty simple with my OpenWRT router.Continue reading Surviving with IPv6 only(4 min read)
