Hosting a website on a PinePhone, etc.

Is carrier-grade NAT being used only for IPV4 addresses, or are they assigning publicly-accessible IPV6 addresses?

That's a good question.  I rather doubt it, but it would be very interesting if they are.

It's so limited though that you'd probably want to run nginx if serious about really doing anything.

You know, on the one hand, I like to usually recommend actively developed software.

OTOH, there are still quite a lot of good tools out there, some of which are "mature / complete" and completely fine just as they are.  Now maybe a web server is perhaps not the best representative of something in this category, and as already mentioned, it depends on use-case, but anyway, I have a better/stronger point to make...

Then there is the hacking aspect.  Something old HAMs and early Linux adopters have always shared.  This curiosity for "seeing if I can get something to work, just because."  A lot of learning have resulted from such "pointless" endeavors.  We are still very early days on GNU/Linux phones, and so this is a very healthy mentality I think to foster at this point in time (well, in general, too).  We want and need hackers, not consoomers.  Whatever our limits as individuals currently are, it's always a good idea to keep pushing them little by little, as that's the only way to learn/grow.
