WebHeader Format – Common Headers p Common values of Next Header field: 0 Hop-by-hop option (extension) 2 ICMP (payload) 6 TCP (payload) 17 UDP (payload) 43 Source routing (extension) 44 Fragmentation (extension) 50 Encrypted security payload (extension, IPSec) 51 Authentication (extension, IPSec) 59 Null (No next header) WebThe Next Header field in the IPv6 header and zero or more extension headers form a chain of pointers. Each pointer indicates the type of header that comes after the immediate header until the upper-layer protocol is ultimately identified. Figure 4-4 shows the chain of pointers formed by the Next Header field for various IPv6 packets.

WebThe last Extension Header’s ‘Next-Header’ field point to Upper Layer Header. Thus all headers from point to the next one in a linked list manner.

The following Extension Headers must be supported as per RFC 2460: WebThe Next Header field is one of the most important additions to the IPv6 datagram format.

WebI imagine this kind of protocol stubbing was its original intended purpose. If the Payload Length field of the IPv6 header indicates the presence of octets past the end of a header whose Next Header field contains 59, those octets must be ignored, and passed on unchanged if the packet is forwarded.
Value 59 (No Next Header) in the Next Header field indicates that there is no next header whatsoever following this one, not even a header of an upper-layer protocol. It means that, from the header's point of view, the IPv6 packet ends right after it: the payload should be empty.
