Community rules (click to expand)
1. Follow the site-wide rules
- Instance-wide TOS: https://legal.lemmy.world/tos/
- Lemmy code of conduct: https://join-lemmy.org/docs/code_of_conduct.html
2. Be civil
- Understand the difference between a joke and an insult.
- Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
- Don't get baited into back-and-forth insults. We are not animals.
- Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
- Bigotry will not be tolerated.
3. Post Linux-related content
- Including Unix and BSD.
- Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of
sudo in Windows.
- No porn, no politics, no trolling or ragebaiting.
4. No recent reposts
- Everybody uses Arch btw, can't quit Vim, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
5. π¬π§ Language/ΡΠ·ΡΠΊ/Sprache
- This is primarily an English-speaking community. π¬π§π¦πΊπΊπΈ
- Comments written in other languages are allowed.
- The substance of a post should be comprehensible for people who only speak English.
- Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
6. (NEW!) Regarding public figures
We all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
- Keep discussions polite and free of disparagement.
- We are never in possession of all of the facts. Defamatory comments will not be tolerated.
- Discussions that get too heated will be locked and offending comments removed.
Β
Please report posts and comments that break these rules!
Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't remove France.

That's a link local address [0].
That's a ULA [1]
This one is a globally routable address (Global Unicast Address, or GUA) [2].
As you observed, link-local addresses are generated completely independently. ULAs and GUAs are self-assigned using SLAAC or assigned by a server using DHCPv6 after your host has seen a router.
For a GUA or ULA to be assigned, the router or DHCP server has to have a prefix delegated to it. A GUA prefix would come from your ISP. A ULA prefix would be configured on the router itself. If yours has one without you setting it up, maybe it does that by default?
