ICMPv6 provides a minimal level of message integrity verification by the inclusion of a 16-bit checksum in its header. The checksum is calculated starting with a pseudo-header of IPv6 header fields according to the IPv6 standard, which consists of the source and destination addresses, the packet length and the next header field, the latter of which is set to the value 58.
ICMPv6 provides rudimentary message integrity through a 16-bit checksum in its header. This checksum is derived from a pseudo-header that includes IPv6 fields as defined by the standard, which encompasses source and destination addresses, packet length, and the next header field set to value 58.
