Upvoted, this seems like a pretty big deal.

I think I've worked on that initial 2013 support within cPanel but didnt understand the final blockers. We didn't have a partner then to test it out. Great to have that fixed finally!

Internally, product leadership at the time had a quandary when it came to IPv6: there was lots of expressed demand for it due to IPv4 depletion looming and “World IPv6 Day/Launch” only about a year or two prior…

…but then, upon delivery, there was nothing. No customer appeared to adopt it even in its rudimentary form. Radio silence. The horsetrading of IPv4 addresses continued and we heard nothing about attempts at adoption for a very very long time.

It got filed away as a feature delivered to calm nerves about lacking that feature…not one that actually provided any forward value. How many other features did we ship that’s soul reason for existing was because lacking it caused discomfort, not because it genuinely helped?

And my residential ISP doesn’t even offer IPv6. Can’t use it even if I want to without someone else’s gateway.

I had a lot of love for cPanel back in the 2000s, when the days of shared hosting and self-installed PHP scripts were in their heyday. Nowadays, though, isn't this just a relic of an earlier time? Who/why would use it for anything today, versus deploying on some PaaS, or Lambda, or.. what have you? Particularly at the prices they're charging.
