I never used IPv6, so I don't know if that applies to IPv6 too or to IPv4 only. In IPv4 it is possible to assign a whole range to a specific machine by adding it as an alias to the loopback interface. For instance, if I do: ifconfig lo:0 192.168.99.32 netmask 255.255.255.224 Then the machine will answer to all the addresses from 192.168.99.32 to 192.168.99.63. If you use a range that is in the same subnet as the IP you have in eth0, it will respond to ARP requests in that interface as well, so it will do exactly what you want. I don't know if and how that would work with IPv6, but maybe try doing that, assigning a single IP with a proper network mask to an alias of the loopback interface and see if that works as you expect.
