Ipv6 header structure
WebThe Internet Protocol (IP) describes the structure of the packets that whizz around the Internet. Each IP packet contains both a header (20 or 24 bytes long) and data (variable length). The header includes the IP addresses of the source and destination, plus other fields that help to route the packet. The data is the actual content, such as a ...
