Hello!

No, if I understood Zdenek correctly, he wants to use the addresses
only internally inside the box, so multiple boxes should happily
co-exist. OTOH if the same address is used anywhere in the neighboring
network, it's going to break.

If the addresses are going to be used only internally, it suffices to
allocate only a small block of addresses and use this block for all
devices.

Sure.
