IP address, or part of it, can never be an ID. so i'm against of
all of the ID/LOC separation stuff.
IP address can never be an identifier because:
- you can switch from one IP version to another
- once you have private address/ULA of some sort, you have conflicts
it is a crazy thought that you have a unique ID in the lower 64 bit in
an IPv6 address. MAC address is indeed not unique - some vendors do
not keep the rules. go down to hongkong/akihabara and buy cheap NE2000
ethernet cards, and you'll know.
if you need to identify some node/whatever, use ssh secret key, X509
certs, and alike. IP address is just to specify communication endpoint,
nothing else.
