It will give out ANY address in the shared network. So addresses in
your 10.1 and 10.2 networks are considered equivalent and any address
can be given to any client. When a client broadcasts to get an
address, then there is no way to know which subnet it "belongs to" -
in reality it doesn't belong to a subnet at all UNTIL it's received
and accepted an offer.
You have to do some work if you want specific clients to get
addresses from a specific network.
