The move to IPv6 wouldn’t be so damned glacial if they had made it backward compatible with IPv4. Choosing not to implement backward compatibility was a serious mistake.
I won’t even bother expending the effort to operate two entirely separate network stacks inside my networks until I have to. Until then, there is zero benefit for me trying to move.
A fired in mine in very high up in the IT dept in a large company in my area, with several different locations. They have said the same thing. The headache for trying to move to IPv6 isn’t worth it. They used to run everything in-house, but have moved things like Email, web hosting, etc. to the cloud that freed up a bunch of IPv4 addresses.
