Set up a virtual NIC, use static IP with one and let the other SLAAC (NOT DHCP, IPv6 obviates the need for DHCP) in a different subnet. Then setup routing as needed so default gateway is on the SLAAC NIC. The real question is why are you concerned with 'randomizing' your IP? The prefix is what people will know you by, and the prefix will not change. All IP-based tracking will recognize you fine after the IP change. > And how to I do this with DHCP for guests (should work with windows > and linux)? Again, DHCP isn't used for IPv6 (although it exists if you need certain requirements like providing a tftp boot rom for PXE) -- Liam
