Two Roles of DHCP

BD.

Sure, I'd be happy to explain the two roles of the Dynamic Host Configuration Protocol (DHCP).

1. DHCP server leases client IP addresses dynamically: One of the primary roles of DHCP is to dynamically lease IP addresses to client devices on a network. Instead of manually configuring IP addresses on each client device, DHCP automates this process by assigning an IP address to the device as soon as it connects to the network. This is particularly useful in large networks with many devices, where manually assigning IP addresses can be time-consuming and prone to errors. The DHCP server keeps track of the IP addresses it has assigned and their lease times. When a lease expires, the IP address can be assigned to another device.

2. DHCP server offers the ability to exclude specific IP addresses from a pool of IP addresses: Another important role of DHCP is to allow the network administrator to exclude specific IP addresses from the pool of IP addresses that can be leased to client devices. This is particularly useful when certain IP addresses need to be reserved for specific purposes, such as servers or network devices. By excluding these addresses from the DHCP pool, the administrator can ensure that they are not accidentally assigned to client devices. Excluding specific IP addresses is also helpful for preventing conflicts with statically assigned IP addresses, which may already be in use on the network.

To summarize, the two roles of DHCP are to dynamically lease IP addresses to client devices and to allow the network administrator to exclude specific IP addresses from the DHCP pool.
