[Answer] What size is an Internet Protocol (IP) v6 payload field?

Answer: 16 bit
What size is an Internet Protocol (IP) v6 payload field?

The fixed and optional IPv6 headers are followed with 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. In practice hosts determine the maximum usable payload length using P…

On the Internet data is transmitted in the form of network packets. IPv6 specifies a new packet format designed to minimize packet header processing by routers. Because the headers of IPv4 packets and IPv6 packets are significantly different the two protocols are not interoperable. However most transport and application-layer protocols need little or no change to operate over IPv6; exceptions are application protocols that embed Internet-layer addresses such as File Transfer Protocol (FTP) and Network Time P…

Mon Feb 12 2007 13:30:00 GMT-0500 (Eastern Standard Time) · The minimum payload is 42 octets when an 802.1Q tag is present and 46 octets when absent. When the actual payload is less padding bytes are added accordingly. The maximum payload is 1500 octets. Non-standard jumbo frames allow for larger maximum payload size. Frame check sequence

Next Header (8 bits) Type of the next header indicating what upper-layer protocol was protected. The value is taken from the list of IP protocol numbers. Payload Len (8 bits) The length of this Authentication Header in 4-octet units minus 2. For example an AH value of 4 equals 3×(32-bit fixed-length AH fields) + 3×(32-bit ICV fields) − 2 and thus an AH value of 4 means 24 octets.
