wouldn't want to go there: - this is IEEE's turf (the above would be an alternate format the the EUI-64 which already includes 24 bits for company_id) - ignoring the top bits (presumably company id) means we can have collisions if we only look at the bottom bits (these bottom bits are only required to be unique within a given company_id space - presumably, the IEEE went for EUI-64 instead of the typical EUI-48 precisely because with 15.4 devices one expects so many of them. cutting back on the number of bits we have to tell them apart (from 64 to 32 per address if I understand your proposal) defeats that purpose - there's an existing alternative: use short 16-bit addresses as specified by 15.4. -gabriel _______________________________________________ 6lowpan mailing list [email protected] https://www1.ietf.org/mailman/listinfo/6lowpan
