Nitpick: The subnet fe80/10 is for link-local addresses (https://en.wikipedia.org/wiki/Link-local_address#IPv6). However, it is not an analog to the RFC 1918 IPv4 subnetworks.

192.168/16 is a private IPv4 subnet (https://en.wikipedia.org/wiki/Private_network#IPv4) and the equivalent for IPv6 is the fd00/8 subnet (RFC 4193).

And with ULAs (fd00::/8) you can pick your own prefix. Officially you should pick a random one to prevent collisions when you connect private networks, but you can choose something memorable if you don’t care about that
