> I hope that operating systems and/or routers will provide the option to rotate each IPv6 address on a routine basis. This is an issue when using SLAAC, yes, but a workaround ("Privacy Extensions") were developed years ago; cf. RFC4941 [0]. You can also assign static addresses or use DHCPv6 -- on your own networks, at least; you obviously can't control how your ISP decides to issue addresses.
