>When the client receives the DHCPACK packet, it begins the binding phase by binding the assigned address to the TCP/IP protocol running on its network card and then finishes booting. At this point, the client can communicate on the network using TCP/IP. The client keeps the TCP/IP address assigned to it for the length of its lease which you can adjust, or until you manually shut it off. If you keep the client running continually, it will eventually reach the end of its lease period.
>
>When the client reaches 50 percent of its assigned lease time, it will enter the renewal phase. The client sends a DHCPREQUEST packet directly to the server that gave it its TCP/IP address. The DHCP server renews the lease and sends back a DHCPACK packet, which contains the new lease and any configuration information that may have changed since the initial lease.

>If the client can't communicate with the server that granted its lease, it will display an error but continue to operate normally. When 87.5 percent of the client's lease time expires, the client begins to panic and enters the rebinding phase.
