How many bytes in a data packet?
IP packets are composed of a header and Payload. The IPv4 packet header consists of: 4 bits that contain the version, that specifies if it’s an IPv4 or IPv6 packet, 4 bits that contain the Internet Header Length which is the length of the header in multiples of 4 bytes. Ex. 5 is equal to 20 bytes. 8 bits that contain the Type of Service, also referred to as Quality of Service (QoS), which describes what priority the packet should have, 16 bits that contain the length of the packet in bytes, 16 bits that contain an identification tag to help reconstruct the packet from several fragments, 3 bits that contain a zero, a flag that says whether the packet is allowed to be fragmented or not (DF: Don’t fragment), and a flag to state whether more fragments of a packet follow (MF: More Fragments) 13 bits that contain the fragment offset, a field to identify which fragment this packet is attached to, 8 bits that contain the Time to live (TTL) which is the number of hops (router, computer or devic
