Want to become a Desktop or Network Engineer?

Then cover all troubleshooting criteria of major elements such as Hardware, Operating Systems, Software, Peripheral devices, RAM, ROM, and Motherboard, etc. During your learning period, don’t forget to learn frequently asked Top 50 Desktop Interview Questions including both hardware and network related questions. Among all major concepts in network engineering courses, we are going to discuss Dynamic Host Configuration Protocol, often written as DHCP in some documents. The main objective of this blog is to highlight some points related to DHCP.

Let’s proceed.

DHCP (Dynamic Host Configuration Protocol) is a dynamic host configuration and network protocol used for maintaining effective communication. This protocol is probably used to improve the IP address accuracy in IT organizations. This protocol permits IP address allocation dynamically. This may increase security concerns but through this, network administrators are allowed to characterize an IP address pool for the employee. Moreover, they can observe the whole system without any execution modifications or crashes.

Through DHCP, one can also allocate the default gateway address, DNS and various other relevant configuration parameters.

Major Features of DHCP

·         DHCP offers quick and programmed IP addresses management across a system.

·         It automatically allocates IP addresses.

·         Furthermore, it decreases the risk of troubleshooting typographical errors due to its accurate IP configuration.

·         DHCP guarantees that the address is utilized only once. This factor reduces the chances of IP conflicts.

·         Entire locations of an organization can be easily administrated through DHCP.

·         If an organization wants to modify its IP addresses, endpoints then, the DHCP is being implemented. DHCP permits efficient modification management. This means, there is no requirement of network configuration on any device upgrading and replacement.

 DHCP in an organization:

 Suppose, there is an organization of a bulky network containing more than 500 desktop systems and the systems are associated with large networks that are not easy to manage. Then, there is a need for IP address allocation, network settings, subnet mask, etc. This manual complex computation needs a lot of time. In such a case, DHCP is implemented to reduce errors and complexity.
