For a short moment, I thought it was a legit teletype…

You are confusing unique local adresses and link local addresses. Unique local adresses can only be configured manually or, in theory, with DHCPv6. On Debian, I edit the file “/etc/network/interfaces.d/<interface name>”:

• auto <interface name>
• iface <interface name> inet dhcp
• iface <interface name> inet6 static

•     address <unique local adress of your choice within the official range>
  

•     autoconf 1
  

•     accept_ra 2
  

•     privext
  

This gives you: autoconfigured IPv4 address, autoconfigured (slaac) IPv6 address, an IPv6 unique local address, temporary IPv6 adresses (privacy extensions) and your IPv6 link local address.

Yes, your ISP provides you a large quantity of adresses. Not really, the adresses has several parts. Your ISP provides you with the prefix. Your devices complete the rest of the address automatically. You can also use a DHCPv6 server, but I don’t and some devices don’t support it anyway. Yes, all those adresses are globally routable, they are “Internet” adresses. You can still use locally routable adresses too if you want, called Unique local address (look it up on Wikipedia), but that requires manual configuration.

If you don’t use IPv6, you are behind. For me the transition was so hard, it’s a big step behind me, wouldn’t want to do it again.

I’m fully transitioned. The first step was getting an Internet provider that featured it. I had to change providers for that. Then I had to find equipment that worked. Some of the things that have an early implementation of IPv6 don’t actually work. It’s like they never actually tested it. Then I had to integrate IPv6 in the way everything worked. I’m a big user of unique local adresses, which I feel isn’t a really well known feature.

I’m surprised by the comments here. I use 90% IPv6. For me v4 is only present for retro compatibility. The transition was hard however.

I’ve been a PC gamer for 32 years now. I do enjoy having a clear side panel. I’ve had one for 22 years. That way you can show off whatever you have inside. I don’t use RGB or any kind of lighting. I just think clear electronics are cool, you can see how they are made.
