Best of luck. The DHCPv6 protocol allows this, in theory, but how it 
should work in practice is not really settled, in my experience. Do you 
have a DHCPv6 client that will do the work? All the clients I've tested 
seem to only request or expect a single address.

dnsmasq-2.66 includes a serious rewrite of the DHCPv6 code which allows 
it to offer multiple addresses. You should use that, or preferably the 
2.67test releases, to have any chance of success.


Certainly don't expect it to "just work", but do report back on the 
results of your efforts: we may be able to help further, and improve 
dnsmasq in the process.


Cheers,

Simon.
