The indicator for whether the IP checksum is valid. If the checksum is invalid, the datagram may 
have been corrupted during transit or may be being used in an intrusion evasion attempt.

The IP address or domain name for the source (or destination) host.

Note that to display the domain name, you must enable IP address resolution; for more information,

The following listing describes protocol-specific information that might appear in an IPv6 packet.

An experimental 8-bit field in the IPv6 header for identifying IPv6 packet classes or priorities 
similar to the differentiated services functionality provided for IPv4. When unused, this field is set 
to zero.

A optional 20-bit IPv6 hexadecimal value 1 to FFFFF that identifies a special flow such as 
non-default quality of service or real-time service. When unused, this field is set to zero.

A 16-bit field identifying the number of octets in the IPv6 payload, which is comprised of all of the 
packet following the IPv6 header, including any extension headers.

An 8-bit field identifying the type of header immediately following the IPv6 header, using the same 
values as the IPv4 Protocol field.

An 8-bit decimal integer that each node that forwards the packet decrements by one. The packet is 
discarded if the decremented value reaches zero.

The 128-bit IPv6 address for the source host.

The 128-bit IPv6 address for the destination host.
