ELI5: ipv6 (feddit.org)

Seriously, my knowledge ends with:

  • It offers a shitload of IP addresses
  • They look really complicated
  • Something about every device in your local network being visible from everywhere?
  • Some claim it obsoletes NAT?

I get that it's probably too complicated a subject for an ELI5, so if there are good videos or resources explaining it in less than half an hour, feel free to share.

You can set up your own IPv6 server, and it will be accessible from every other IPv6 device. Do you want to create a Lemmy server using only your phone and Verizon mobile data? Yes you can! *

* Instructions for installing Linux environment on Android phone and setting up free DNS and HTTPS certificates are not included.

That's the main point. IPv4 fails because half of all existing IPv4 devices cannot access the other half of IPv4 devices directly, they have to go around using some kind of relay server, which inevitably complicates communications and costs extra money.
