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.

It's just a larger address space, nothing particularly special. Just more numbers

If you use IPv6, you don't need to have concepts like rfc1918 / "private ip spaces, so if every ip is unique, they can be used publicly you don't need NAT

I'm guessing you don't need DHCP anymore either?
What's the difference between an ipv6 address and a MAC address then?

[–] ChairmanMeow@programming.dev 2 points 5 days ago

Different network layer. MAC addresses are layer 2 iirc, whereas IPv6 is layer 3.
