I was told that an IPv6 link-local address — those typically starting with `fe80::` — is derived from the interface's MAC address. [Here](https://ben.akrin.com/mac-address-to-ipv6-link-local-address-online-converter/) are some instruction on how to do the conversion.- But the conversion result doesn't match my actual IPv6 link-local address according to `ip a`. My IPv6 link-local addresses and MAC addresses don't seem related at all.

- I'm on Arch Linux using NetworkManager 1.42.6.
