I don't think ANY client supports it directly, out of the box - and
I'd be VERY surprised if it was possible to get the Windows client to
do it (at least for it's own use). I don't know if the ISC client
will do it easily - but it will definitely need some manual
Personally, I suspect that by the time you've manually configured the
client to request multiple addresses and configured the dhcp server
to give fixed address, it would have been quicker and easier to
manually configure the client with IP addresses.
