>IPv6 not being supported in many places means the internet is more centralised, less likely to use proper p2p tech-
Realistically nobody outside some devoted HN readers are going to self host their own content. At best you'd see something like netflix trying to offload their video hosting costs onto their customers.
Well yeah, because they can't. Maybe if they could, they would do it more. You probably wouldn't want to host a permanent website from home, although some people do, but you could share a file. It would be popular with game servers, too.

bittorent has been around for decades and nobody used it. They emailed files to themselves instead, or used dropbox. This all happened before the ipv4 shortage and people getting moved to CGNAT.
I think the commenter you’re replying to is pointing out that nobody used BitTorrent for legitimate cases. And that take is sadly correct. Despite having huge upsides, everyone just hosts on centralized CDNs, file syncing services (gdrive, Dropbox, etc).
Even Linux distros push you so direct downloads now rather than pointing to trackers.
BitTorrent only has healthy usage for content that’s untenable to host legitimately.
You sure you don't have this reversed? The average person uses the internet to watch tiktok videos and join zoom meetings, all of which is centralized. The people self hosting their NAS or minecraft server is a tiny minority.
IPv6 doesn't solve the Airdrop problem. It'll only work at reasonably-fast speeds in the rare case that both people are connected to the same wifi network - but there's already tools like LocalSend[0] for that. Having a file go via cellular provider A, halfway across the country, through some IX, halfway across the country back, and via cellular provider B tends to make things a bit slow.
Similarly, using P2P for game VOIP is a Really Bad Idea as it basically doxxes the player. Even 1v1 lobbies aren't always with people you trust enough to invite them into your house, so you shouldn't be handing them your IP address! In 99% of cases it is better to proxy it via a server instead.
Brother, if I can do something to you based on your IP address you are already totally fucked.
This whole "the thing that I use to be addressed on the internet is dangerous" myth needs to die. It's a telephone number, not a home address. You can block numbers.

P2P is not “self hosting”.
It’s video/audio conferencing working with less latency. It’s the ability to send a file directly and not via some file sharing site. It’s multiplayer gaming simplified. It’s faster software updates via BitTorrent.
Obviously I can't see the future, and I live in my own bubble....
Isn't self hosting, and small, private/semi-private communities the only way forwards for much of the internet? AI has made content extremely valuable, which in turn has started to destroy the openness of the web. Things are getting more and more siloed, with entry fees.
There's a world where self hosting comes back in a big way. AI ironically makes it much easier.
Someone DDoSing the $10 VPS hosting my personal website is no big deal. I don't care about it strongly enough that it must stay online, so they'll eventually get bored and move on.
Someone DDoSing my home internet connection? That's going to be a serious inconvenience - especially with WFH. No internet for a week isn't an option.

How about Xbox/PS multiplayer/P2P gaming? Hosting a Minecraft server?
When Skype first came out it was P2P, but had to come up with the "supernode" concept (basically STUN/TURN/ICE) because of NAT: now all of our communication methods basically have to phone into the mothership.
Do we want the Internet to be more centralized (possibly given more power to the tech bros) or more decentralized?
Would you give your personal phone number to random strangers on the internet, or even publish it on a website? Probably not, due to the possibility of harassment, right? IP addresses aren't any different, which immediately kills a huge portion of the game server self-hosting.
A hosted and managed Minecraft server is available for less than the cost of a cup of coffee per month. At that price point it makes very little sense to deal with the hassle of having to run your own home server. Even if you want to geek out and manage it yourself, a VPS is a very attractive option.
And for the handful of people that remain and really want to homelab a Minecraft server for their friends but are stuck behind CGNAT, there's always software like Hamach - which solved the gaming NAT problem back in 2004.
So no, self hosting isn't a problem which needs IPv6 to solve it.
> Would you give your personal phone number to random strangers on the internet, or even publish it on a website? Probably not, due to the possibility of harassment, right? IP addresses aren't any different
1. The claim that IP addresses aren’t different from the phone numbers requires proof
2. Until very recently, just before the Covid pandemic people regularly exchanged physical business cards with their mobile phone numbers. So, yes, people do that.

You talk of a singular number in this analogy, but that is completely non-sensical in the IPv6 context: even brain dead ISPs assign /64s to residential connections, so you could give random strangers a random IPv6 address that's valid for a few hours and then you remove it from service.
Want to provide a service? Generate a new address, assign it to the server, publish it to whomever you wish. When you're done remove the ip addr alias. Give each rando their own IPv6 address for the service that's only live for a finite amount of time.
In fact you could generate a new IPv6 address each second in your assigned /64 and you wouldn't run out for 584,942,417,355 years.
