This is an incredibly niche concern, but I fought to get IPv6 working for myself because I have an EC2 instance that auto-sleeps when I'm not using it (to save money) and every time it wakes up the IPv4 address changes. Amazon will give me a static address but unless the machine is running the static address costs money. Again the whole point was to save money... and static IPv6 addresses are free on AWS.

So as long as I connect to the EC2 instance over IPv6, I get a free static IP address on my server.

That's a direct side affect of the difference in cost between IPv4 addresses and IPv6 addresses. If IPv4 addresses weren't economically rare, AWS would charge for them.

Does anything prevent you from using a free DynDNS provider?

There were a number of good choices. I chose ipv6 mostly because I wanted an excuse to try ipv6. I did consider dynamic dns but didn’t explore it much.
