Re: Thanks, but no thanks
The right-hand half will be randomly generated and change regularly due to privacy extensions, so it'll change even if you don't move between networks.
Well now, maybe, but in yearly times the use of EUI-64 to set the system ID half of the IPv6 address shows that early on people in the IPv6 world weren't thinking of this issue.
RFC7217's stable privacy extension provides different system IDs when a node moves between networks but stable addresses while on a network. If the whole address is changing how are systems going to be able stay connected to you?
