An IP header is header information at the beginning of an Internet Protocol (IP) packet. An IP packet is the smallest message entity exchanged via the Internet Protocol across an IP network. IP packets consist of a header for addressing and routing, and a payload for user data. The header contains information about IP version, source IP address, destination IP address, time-to-live, etc. The payload of an IP packet is typically a datagram or segment of the higher-level transport layer protocol, … WebIPHDR->IHL Header Length (4 bits): The header length refers to the number of characters in the IP layer header (that is, the IP layer header contains 4 bytes – 32 bits), including any options. Because it is a 4-bit field, the header is up to 60 bytes long.
