The fixed and optional IPv6 headers are followed by the upper-layer payload, the data provided by the transport layer, for example a TCP segment or a UDP datagram. The Next Header field of the last IPv6 header indicates what type of payload is contained in this packet. The payload length field of IPv6 (and IPv4) has a size of 16 bits, capable of specifying a maximum length of 65535 octets for the payload.
