I'm guessing that the 5 IPs you have are part of a /29 subnet - with 
the other 3 accounted for by the subnet, broadcast, and router 
addresses. If this is the case, then you also almost certainly have 
fixed address and should be able to just configure them statically.

One other (sledgehammer) approach I can think of might be to stick a 
few extra ethernet cards in the machine !
