Re: why did IPv6 use 128bit Hex?
>IPs would be used like IMEIs/IMSIs/MACs? No, that's specifically not what IPs are used for
There is a important distinction between what IPv6 addresses are now being used for and the ideas that were swimming around in the 90's when it was envisaged that IPv6 addresses could be static and thus could embed IMEI's, MAC addresses, phone numbers etc. to allow all of these to be used in IP communications. It is only a small step to say that the IMEI, MAC etc are just short forms of unique IPv6 addresses and thus say IPv6 addresses could be used as IMEI, MAC etc.
