One added advice for the addressing plan: don't get too complicated.
KISS is a great principle - eg for Iljitsch's advice "Allocation::/48
is ourselves" is simple.
Trying to code the make of the device into the address is not.
And don't attempt to conserve addresses as hard as you would with IPv4. :)
Simple should win over less address use while you still manage to keep
about a quarter of your allocation as planning reserve for changes.
