Detailed explanation-1: -Explanation: The IP address offered to a client is only for a limited period of time. There is actually a certain amount of time that the client can use and keep this IP address.
Detailed explanation-2: -DHCP servers usually assign each client with a unique dynamic IP address, which changes when the client’s lease for that IP address has expired. There are many enterprise companies who are still using DHCP for IPv4 on their routers/switches.
Detailed explanation-3: -The IP address information assigned by DHCP is only valid for a limited period of time, and is known as a DHCP lease. The period of validity is called the DHCP lease time.
Detailed explanation-4: -The DHCP server responds to the client request by providing IP configuration information previously specified by a network administrator. This includes a specific IP address, as well as a time period–also called a lease–for which the allocation is valid.
Detailed explanation-5: -Following are the disadvantages of DHCP: ➨DHCP server can be single point of failure in networks having only one configured DHCP server. ➨DHCP packets can not travel across router, Hence relay agent is necessary to have DHCP server handle all leases on both network segments.
