NAT don't have anything how you manage your inside network or control'it ..
DHCP will not masquerade your ip's
DHCP is Dinamyc Host Control Protocol this way you cand control the
hosts .. or you can control manualy configuring each host or use
Conextualization scripts to have ip's form your opennebula lesses
