Many operating systems use the EUI-64 algorithm to generate IPv6 addresses. This algorithm derives the last 64 bits of the IPv6 address using the MAC address. Many see this as a privacy problem. The last half of your IP address will never change, and with MAC addresses being somewhat unique, the interface ID becomes close to a unique “cookie” identifying your system.
