Therefore, on your home network, your router serves as a simple DHCP server that assigns this information to hosts. These assignments typically only last for a limited time (an hour to a week usually) and so you are never guaranteed that the IP address for a particular computer will remain the same when using a DHCP (some DHCP servers allow you to specify that a computer gets the same address all the time however). These DHCP packets are handled in software (not hardware accelerated forwarding). It allows several devices to connect to a network over a period of time without needing a pool of available addresses. Router, on the other hand, is used to connect to the Internet.
