Note :
The Internet Protocol (IP) itself does not provide error recovery. It relies on higher layers, such as the Transmission Control Protocol (TCP), to ensure data integrity and error recovery.
The IP header includes a checksum to verify the integrity of the header information. This checksum is a form of error detection, ensuring that the header has not been corrupted during transmission. However, it does not provide error recovery; it only detects errors in the header.
