I am sorry I was playing with words.
 
DHCP stands for Dynamic Host Configuration Protocol.
So it is like saying 
Static Dynamic Host Configuration Protocol.
I any case what Entry Level Cable/DSL Router can do what is referred to as IP Reservation.
Which means that if you use the Router?s DHCP server to assign IPs as long as you do not Reset the Router it will maintain the same IP associated with the MAC of the computer that obtained it first. 
You can also assign a Static IP  to a specific computer in the computer?s Network Setting, and as long as it within the subnet of the Router, but out of its  DHCP server assigning range it will honor by the Router.
