Hello! > So what happens when you put tow or three of Zdenek's boxes in one > location? Back to square 1? 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. > Except this wont be practical for IPV4 since those addresses are scarce. 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. > May make sense for V6 though (becomes like MAC addresses on NICS).
