I suspect I am going to be running dual stack for at least the next decade, IPv4 switch off feels very far away. I don't think there is much advantage or disadvantage to running IPv4 compared to translation. The current internet doesn't feel ready. I have had less issues with IPv6 this year compared to last so there has been some progress but I am still getting fallbacks to IPv4, some companies don't seem to care much about IPv6 outages currently.

I can’t understand benefits of having ipv6. The only one is public ips but rest is just headache. In my home network I specify disabled v6 everywhere.

Where I live, the benefit of IPv6 is it's a lot faster than IPv4. All of IPv4 goes through various centralized tunnels and CG-NAT which adds bottlenecks and latency.

A site-to-site VPN of two previously unrelated local networks is a pure gamble with IPv4. It would be almost straight forward with IPv6.

It doesn’t matter in home networks, it’s a major pain in the ass if you are a Fortune 500 company and want to set up more intercompany vpn links

Finally. I will now be able to run ~340 undecillion devices on my home network. I'll have the smartest "smart home" on the block.

I never understood the rationale of giving out /64 and /48 like candy after what happened with ipv4. I know it's still a massive increase in capacity and I know it makes the networking easier but it seems like we went from something that definitely won't run out (ipv6 addresses) to something that probably won't (number of /48 ranges)

IPv4 pricing isn't a good enough reason? If all of my devices had nice ipv6 connectivity I could ditch the public ipv4 addresses, but I have to keep them so that my ipv4-only devices can still reach them.

I messed with this at one point and gave up when I realized every device would have a permanent externally addressable IP within a block that is basically linked to me (good luck trying to change your IPv6 /48 every month or whatever you get with consumer IP addresses)

It’s probably not a big deal and NAT etc. is no protection but it gave me the heebie jeebies.
