That's not typically true. The usual case is that RFC 4941 Privacy
Extension addresses are turned on, and each computer generates a new
ephemeral address every 24 hours to use for outgoing connections. Since
the address is random there's no information in it to identify the
specific computer.

(Given the list I'm posting this to, I should mention the non-typical
case: privacy extensions are enabled by default on Windows but not on
Linux. Enable them by setting net.ipv6.conf.<interface>.use_tempaddr=2)
