Extension headers form a chain, using the Next Header fields. The Next Header field in the fixed header indicates the type of the first extension header; the Next Header field of the last extension header indicates the type of the upper-layer protocol header in the payload of the packet. All extension headers are a multiple of 8 octets in size ...
The IPv6 packet header has a minimum size of 40 octets (320 bits). Options are implemented as extensions. This provides the opportunity to extend the protocol in the future without affecting the core packet structure. [2] However, RFC 7872 notes that some network operators drop IPv6 packets with extension headers when they traverse transit ...
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.

Static Context Header Compression (SCHC) is a standard compression and fragmentation mechanism defined in the IPv6 over LPWAN working group at the IETF. It offers compression and fragmentation of IPv6 / UDP / CoAP packets to allow their transmission over the Low-Power Wide-Area Networks (LPWAN) .
An example of the fragmentation of a protocol data unit in a given layer into smaller fragments. IP fragmentation is an Internet Protocol (IP) process that breaks packets into smaller pieces (fragments), so that the resulting pieces can pass through a link with a smaller maximum transmission unit (MTU) than the original packet size.
6LoWPAN (acronym of "IPv6 over Low-Power Wireless Personal Area Networks") [1] was a working group of the Internet Engineering Task Force (IETF). [2] It was created with the intention of applying the Internet Protocol (IP) even to the smallest devices, [3] enabling low-power devices with limited processing capabilities to participate in the Internet of Things.
For such use cases, a special notation has been introduced, which expresses IPv4-mapped and IPv4-compatible IPv6 addresses by writing the least-significant 32 bits of an address in the familiar IPv4 dot-decimal notation, whereas the 96 most-significant bits are written in IPv6 format. For example, the IPv4-mapped IPv6 address ::ffff:c000:0280 ...
