Configuring Network Interface with DHCP in Router

What is DHCP used for in network configuration?

a. Assigning static IP addresses
b. Automatically obtaining IP addresses
c. Configuring DNS settings
d. Securing network connections

Answer:

b. Automatically obtaining IP addresses

Dynamic Host Configuration Protocol (DHCP) is a network protocol that automatically assigns IP addresses to devices on a network. This simplifies network configuration by eliminating the need for manual IP address assignment. With DHCP, devices can obtain IP addresses dynamically, making it easier to manage and maintain large networks.

When a device connects to a network with a DHCP server, it can request an IP address from the server. The DHCP server then assigns an IP address to the device for a specific lease period. This helps in efficient utilization of IP addresses and ensures that devices on the network have unique addresses.

By using DHCP, administrators can streamline network management, reduce errors in IP address assignment, and ensure that devices are always properly configured with the latest network settings. This protocol plays a crucial role in simplifying the process of configuring network interfaces, such as in routers, switches, and computers.
