> What tangible benefits have you reaped from IPv6 that simply weren't possible on IPv4?

Personal networks: Globally unique addressing. That then lends itself to not needing any kind of split DNS for services, or worrying about addressing clashes with whatever LAN I happen to be on with my own network.

Work networks: Increased revenues.

> Has the ROI for you on going dual stack outweighed the costs on your time, attention, and configuration work required for securely handling edge cases, dealing with weird or unexpected routing issues, for straying from the happy path?

Personal networks: Absolutely not. I removed the dual stacks and went back to IPv4 only everywhere.

Work networks: That's a question for the bean counters.
