because, in the end, ULA (whichever flavor it is) leads to
did you read the thread some months ago? There was mention ID and LOC
splitting. ULA fits that idea almost perfect.
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,
