But tcp/ipv6 is API compatible with tcp/ipv4? You can even accept ipv4 connections to a ipv6 listening socket if you have a ipv4 address assigned. The issue is ipv4 is not forward binary compatible with ipv6 because you can't fit more than 2^32 addresses in a ipv4 packet.

But yeah if you are a large bloated enterprise like amazon or microsoft that owns large amounts of ipv4 address space and expensive ipv4 routing equipment there is not a ton of value in switching
