What Is The Reason Why The DHCP Request Message Is Sent As A Broadcast During The Dhcpv4 Process?

To say that the IP addresses are leased, the DHCP request is sent as a broadcast during the DHCPV4 process. Now, let us discuss how the DHCPV4 process works. In order to understand that concept, let us first look at the TCP/IP network configuration in detail. Let us take windows as an example, open the windows command prompt and type “ipconfig/all and press enter. And we have the connection information that is assigned to the wireless adapter. It shows the physical address, IP address, subnet mask, lease obtained, and many. Now, we can use these connection configuration credentials for the whole day. We have some additional addresses like the IP address of the default gateway, DHCP server and we have DNS servers. These are useful for connecting the Internet.

Now, let us know how the DHCP is used. DHCP stands for dynamic host configuration protocol. This allows the DHCP server to set the TCP/IP network automatically for the client computer. If there is no DHCP technology, the IT guy would set up all the configuration values in a computer. The process we perform for the manual setup for a client computer, we call this as the static addressing. It will be a very difficult process to connect to a network without using DHCP. Now, let us discuss the process of the DHCP step by step. We have a DHCP client and the DHCP server. Whenever the client computer boots up, it will broadcast the DHCPDISCOVER message. It doesn’t care where the client’s computer is present. It may be at the home, station, or at any other place. It would send this packet looking for the DHCP server. The broadcast is the way in order to notice the IP address where we notify the destination’s IP address. Suppose, the destination’s IP address is 255.255.255.255. Now, the DHCPDISCOVER packet will simply or ask if there is any DHCP server present and informs that it wants to connect to the internet.

Let say that if a DHCP server is present nearby and if hears the DHCPDISCOVER message. Then the DHCP server responds to the client with a DHCP offer message. This is simply a broadcast UDP. UDP stands for user datagram protocol. It replies back as an acknowledgment message by agreeing to the leasing of the IP address and subnet mask. So that we can connect to the local area network. And we can also say that the IP address is the default gateway and we can connect to the internet and lease it for the 2days. we can also renew the lease after we use it for the 2 days. And now, the DHCP client responds to the message with the DHCPREQUEST. It will simply say that it is accepting all the TCP/IP information. And in the final step, the DHCP server will reply back to the DHCPACK message. It is nothing but the acknowledgment of the packet.
