Which component is responsible for assigning IP addresses in a network?

• A. Switch
• B. Router
• C. DHCP server
• D. Firewall

Answer: (C)

The component responsible for assigning IP addresses in a network is the DHCP server. DHCP, which stands for Dynamic Host Configuration Protocol, automates the process of assigning IP addresses to devices on a network. When a device connects to the network, it sends a request for an IP address to the DHCP server. The server then leases an IP address from a predefined range and sends the necessary network configuration parameters back to the device, such as the subnet mask, gateway, and DNS server information. This process significantly simplifies network management, especially in larger networks, as it reduces the need for manual configuration of IP addresses, which can lead to conflicts and errors if managed incorrectly. In contrast, while routers can assign IP addresses, they typically do so as part of their functionality as a DHCP server only when configured in that manner. Switches primarily function at the data link layer and facilitate the forwarding of data between devices on the same network but do not assign IP addresses. Firewalls are security devices that monitor and control incoming and outgoing network traffic based on predetermined security rules, but they do not handle IP address assignment.
