Explanation:
Detailed explanation-1: -Explanation: The Hop limit value is decremented by one by a router when the datagram is forwarded by the router. When the value becomes zero the datagram is discarded. The field is 8-bits wide, so an IPv6 packet can live up to 255 router hops only.
Detailed explanation-2: -The IPv6 main header is required for every datagram. It contains addressing and control information that are used to manage the processing and routing of the datagram.
Detailed explanation-3: -The fixed header contains the mandatory essential information about the packet while the optional headers contain the optional “not that necessary” information.
