Introduction:
The Internet Control Message Protocol (ICMP) is an integral part of the Internet Protocol Suite. It is used to report errors, perform diagnostics, and exchange control messages between network devices. ICMP has been designed to compensate for various functionalities, including error reporting, error correction, and host and management queries.
Error Reporting:
ICMP provides error reporting capabilities to network devices. Whenever an error occurs during the transmission or processing of IP packets, ICMP messages are generated and sent to the source IP address. These error messages help to identify and diagnose network issues, allowing for timely resolution.
Error Correction:
ICMP also facilitates error correction mechanisms. For example, when a packet encounters an error during transmission, such as a time-to-live (TTL) exceeded or destination host unreachable, ICMP messages are sent back to the source IP address to inform the sender about the error. This allows the sender to take corrective actions, such as retransmitting the packet or choosing an alternative route.
Host and Management Queries:
In addition to error reporting and correction, ICMP supports host and management queries. ICMP messages can be used to query network devices for information or perform diagnostic tasks. For instance, the Internet Control Message Protocol Echo Request (ICMP Echo Request) is commonly known as a "ping" request. It is used to check the reachability and response time of a network host. ICMP also provides other query messages, such as Address Mask Request, Timestamp Request, and Router Solicitation, which serve various network management and troubleshooting purposes.
Conclusion:
In conclusion, the Internet Control Message Protocol (ICMP) has been designed to compensate for error reporting, error correction, and host and management queries. It plays a crucial role in maintaining network stability, diagnosing issues, and facilitating communication between network devices. The various ICMP messages ensure that errors are reported, corrected, and that network devices can query each other for information or perform diagnostic tasks.

IP by itself does not provide the features of error reporting or error correction. So, to address these issues a network layer protocol called Internet Control Message Protocol is used. ICMP operates over the IP packet to provide error reporting functionality.
