This of course depends on your modem/router - I have a broadband modem/router 
from Netgear, and none of their router products support this part of DHCP.

You can also set a longer timeout so that the DHCP server takes a week before 
it changes the IP address for a MAC address. For most people this is 
adequate, as each time you connect, the timeout is reset to whatever value 
you have set. Again, the Netgear doesn't support it, but the old Asus 6000EV 
unit that my father has, does, albeit not from the web interface, but through 
a bit of poking around the telnet console.
