undefined | Better HN

But this is only because everything mainstream that is P2P uses some kind of a centralized relay server. P2P would be much much cheaper for everyone if everyone used IPv6, so it makes a difference.

Tell that to management. As soon as they hear "P2P" they will decide to perpetuate the status quo that makes P2P hard, because P2P is evil and illegal in their books.

And we sit here wondering why the powers that be are not interested in faster IPv6 adoption. Few if any of the reasons we exchange on HN have any bearing outside of this bubble. A typical business in 2022 still has no incentive to embrace IPv6, facilitate P2P, or make the internet more decentralized.

How would you facilitate P2P in an IPv6 world? Do you stop using a firewall and just let anyone open connections to your machine on any port from the internet? If not, how do you allow connections from peers but not random botnets?

Not to mention, would you really use IPv6 addresses that your ISP assigns for your internal network as a business? Do you really want to re-IP everything if you find a way to switch ISPs?

How would P2P work any different in an IPv6 world? You still need to open a port for each incoming connection, which still isn't secure unless the target machine is explicitly requesting this.

I dunno how true that is gonna be. P2P clients will still have to traverse a firewall that may do deep packet inspection. A lot of the problems faced by P2P will still exist even in a pure IPv6 world.
