@mdione @goetz @claushc Here's my #IPv6 primer for people with a technical background:

Some year I'll move it to some other format.

@mdione @goetz @claushc The fe80:: address is just Link Local so won't give you any useful connectivity -- it just exists by default for all links,
For your use-case of wanting local connectivity for when the internet is down, having ULA IPv6 can be useful. One way to do that is to configure your router to announce a ULA /64 prefix (per VLAN) via RAs and then devices should pick an address from it via SLAAC.
