To propose a lease of an IP address to a DHCP client

Explanation:

 The main purpose of the DHCPOFFER message is that during lease time, the DHCP server can't allocate that IP address to some other customers. The main purpose behind a lease is to restrain the time allotment that a customer can utilize an IP address in the DHCPv4 process.

The DHCPv4 client can decrease an idea from a DHCPv4 server in the event that it confirms that the IP address incorporated into the DHCPOFFER message sent by the server is as of now being used on that arrange.

Provided that this is true, the DHCPv4 customer sends a DHCP DECLINE message and then restarts the setup procedure by sending a DHCP DISCOVER message once more
