Address Release process in DHCP

In the address release process, the BOUND state operates as the normal state, so when a client typically remains in the BOUND state while it uses the IP address which it has acquired. If a client has the secondary storage, the client can store the IP address which was assigned and it requests the same address when the system is restarted. In some cases, a client is in the BOUND state may discover that it is no longer needing the IP address. If we take an example then, if a user attaches a portable computer in the network then it uses the DHCP to acquire the IP address and then it uses the TCP/IP for reading the electronic mails. So, the user may not know that from how long reading the mail will be requiring or the portable computer may allow the server to choose the lease period. In any case, the DHCP specifies a minimum lease period of 1 hour. If even after obtaining the address, the user discovers that no email messages are waiting to be read, the user may choose to shutdown portable computer and move to another location.
So, when it no longer needs the lease, the DHCP allows a client to terminate the lease without waiting for lease to get expired. Mainly, such kind of terminations help where neither the client nor the server can determine the appropriate lease duration at the time the lease is granted because it allows the server to choose a reasonably long lease period. Early lease termination is very important if the number of IP addresses the server has available is much smaller than the number of computers which are attached to the network. If here each client terminates its lease as soon as the IP address is no longer needed, the server will be able to assign the address to another client which requires the same. For terminating the lease early, a client sends a DHCPRELEASE which leaves the Bound State and again need to initialize the state before it can use the IP address.
