alt Hacker NewsYou can't selectively use IPv6 in the WAN and IPv4 in the LAN.
How would an IPv4 client send a packet to an IPv6 server? The IPv4 packet has only 4 bytes to spare for the destination address.
You can't.
Anything longer, even if it's just 1 bit, would require a new IP version.

You can run a 4to6 NAT, where specific v6 addresses (the ones you’re talking to) are aliased to reserved v4 addresses out of the PUA.

The "solution" is that IPv6-only servers do not exist and will never exist.
