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, … WebWhat is an IP packet? IP packets are created by adding an IP header to each packet of data before it is sent on its way. An IP header is just a series of bits (ones and zeros), and it records several pieces of information about the packet, including the sending and receiving IP address.
