WebIf there are no more extension headers, the next header field indicates the upper layer header (TCP header, User Datagram Protocol [UDP] header, ICMPv6 header, an encapsulated IP packet, or other items). For information on IPv6, refer to RFC 2460. IPv6 Addressing IPv6 uses a 128-bit addressing model. WebThe next Header signifies the Extension Header type; in some cases, when the Extension Header is not present, it signifies the protocols present inside the upper layer packet like UDP, TCP, etc. UDP (17) and TCP (6) are the most common Next Headers, but other types of headers are also possible. data structures types in pythonWebIPv6 Header Chain: The IPv6 Header Chain contains an initial IPv6 header, zero or more IPv6 Extension Headers, and optionally, a single Upper-Layer Header. If an Upper-Layer Header is present, it terminates the IPv6 Header Chain; otherwise, the "No Next Header" value (Next Header = 59) terminates it. data structures using c 2nd edition
