What protocol is primarily utilized for automatic IP address assignment?

• A. ARP
• B. ICMP
• C. DHCP
• D. DNS

Answer: (C)

The protocol that is primarily utilized for automatic IP address assignment is Dynamic Host Configuration Protocol, commonly known as DHCP. This protocol enables network devices, such as computers and smartphones, to automatically receive an IP address and other necessary configuration settings, such as subnet mask, default gateway, and DNS server addresses. When a device connects to a network, it sends out a DHCP discovery packet to request an IP address. The DHCP server will then respond by offering an IP address from its pool of addresses. After that, the device sends a request to accept the offer, and the server acknowledges this, thus completing the assignment of the IP address. This process makes managing IP addresses much simpler, especially in networks with a large number of devices, as it minimizes the risk of address conflicts and manual configuration errors. Other protocols mentioned serve different purposes: ARP (Address Resolution Protocol) is used to map IP addresses to MAC (Media Access Control) addresses within a local network. ICMP (Internet Control Message Protocol) is mainly used for network diagnostics and error reporting, such as the tools ping and traceroute. DNS (Domain Name System) resolves domain names to IP addresses but does not assign IP addresses itself. These distinctions highlight why DHCP is the correct answer for automatic IP
