Abstract
The problem of wasting IP addresses by statically assigning them to hosts is solved as follows: when a cable router or RF modem becomes active, it sends a message requesting a set of IP addresses from the head end, which dynamically assigns the set of IP addresses and sends a message comprising the set of IP addresses to the cable router or RF modem. The cable router or RF modem then responds to requests by the hosts for IP addresses by assigning them IP addresses from the set. Furthermore, the set of IP addresses is released when the session terminates with the cable router or RF modem.
