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. Standard payload length The payload length field … See more An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 … See more Unlike in IPv4, IPv6 routers never fragment IPv6 packets. Packets exceeding the size of the maximum transmission unit (MTU) of the destination link are dropped and this condition is signaled … See more The fixed header starts an IPv6 packet and has a size of 40 octets (320 bits). The bytes of the multi-byte fields are in the network byte order. Fixed header format … See more Extension headers carry optional internet layer information and are placed between the fixed header and the upper-layer protocol header. … See more WebIPv6 Extension Headers In IPv6, optional internet-layer information is encoded in separate headers that may be placed between the IPv6 header and the upper- layer header in a packet. There is a small number of such extension headers, each one identified by a distinct Next Header value.

Operational Implications of IPv6 Packets with Extension Headers
WebThere are two main parts to the IPv6 data packet that is header and payload. The header of IPv6 is of fix length of 40 bytes which has the following fields: Refer to the below image for the components of the IPv6 header. Version; Traffic … WebIt also discusses Extension headers, which are new in IPv6. The header structure of an IPv6 packet is specified in RFC 2460. The header has a fixed length of 40 bytes. The two fields for source and destination addresses each use 16 bytes (128 bits), so there are only 8 bytes for general header information. WebEach 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 … diagram of human teeth with numbers
