>IPv6 doesn't make things substantially harder, just different. But people don't want to learn new things I learn new things all the time. IPv6 is much more complicated, and importantly, more complicated than it needs to be. There is really no reason for most devices to be publicly reachable. Everyone keeps holding this up as a positive, but it's absolutely not. Most devices aren't servers. Yes, a firewall can prevent these connections, but the whole standard is built around this use case most people don't need most of the time. Private IP space is incredibly useful. I build it and set it up -- my ISP does not have control. This is _gone_ with IPv6 and it makes things much more complicated than they need to. |
Ever tried to call someone over the internet? Well, now you need a publicly reachable device.
Please, stop spreading this ignorance. You rely on your devices being reachable from the internet every single day, you're just not aware of it, because you're using a barely-working pile of duct tape and string that sort-of allows peer to peer connections to happen, after some arcane STUN/TURN/whatever magic.
If you wanted to send someone a file in the Olden Days, you'd just click on their IRC username, the client would open a connection to them and you'd send the file. Now you need to use iCloud or some nonsense, because apparently people believe that peer-to-peer connections aren't needed and shouldn't even work.
