 The payload of the IP packet contains the actual data being transmitted. The length and structure of the payload depend on the protocol specified in the Protocol field of the IP header. For example: The payload of the IP packet contains the actual data being transmitted. The length and structure of the payload depend on the protocol specified in the Protocol field of the IP header. For example:
-- If the Protocol field indicates TCP (Protocol number 6), the payload will contain a TCP segment. + 
-- If the Protocol field indicates UDP (Protocol number 17), the payload will contain a UDP datagram. +If the Protocol field indicates TCP (Protocol number 6), the payload will contain a TCP segment. 
-- If the Protocol field indicates ICMP (Protocol number 1), the payload will contain an ICMP message.+
