Maybe, but not necessarily.  It's possible to have both on one LAN.  On this 
LAN, for instance, we prefer to use static IP.  All our boxes have static 
addresses.  However one work laptop needs dhcp to access a company network.  
We tell the router to reserve the addresses that we use statically, and it 
issues addresses outside those to a dhcp box.
