WebIdentifies the type of header that immediately follows the IPv6 header. Uses the same values as the IPv4 protocol field. Hop limit – 8-bit unsigned integer. Decremented by one by each node that forwards the packet. The packet is discarded if the hop limit is decremented to zero. Source address – 128 bits.
