The IPv6 header is a simplification of the IPv4 header.
| Field Name | Type | Description |
|---|---|---|
| IP_Version0..1 | IPVersionType |
4-bit Internet Protocol version number =6. |
| Traffic_Class0..1 | HexBinaryObjectPropertyType |
8-bit traffic class field. Available for use by originating nodes and/or forwarding routers to identify and distinguish between different classes or priorities of IPv6 packets. http://tools.ietf.org/html/rfc2460#section-7. |
| Flow_Label0..1 | HexBinaryObjectPropertyType |
20-bit flow label. Used by a source to label sequences of packets for which it requests special handling by the IPv6 routers, such as non-default quality of service. http://tools.ietf.org/html/rfc2460#section-6. |
| Payload_Length0..1 | HexBinaryObjectPropertyType |
16-bit unsigned integer. Length of the IPv6 payload (the rest of the packet following the IPv6 header) in octets. Any extension headers are considered part of the payload. |
| Next_Header0..1 | IANAAssignedIPNumbersType |
8-bit selector. Identifies the type of header immediately following the IPv6 header. Uses the same values as the IPv4 protocol field. |
| TTL0..1 | PositiveIntegerObjectPropertyType |
TTL/hop limit specifies how many times a packet can be forwarded. 8-bit unsigned integer. |
| Src_IPv6_Addr0..1 | AddressObjectType |
128-bit address of the originator of the packet. |
| Dest_IPv6_Addr0..1 | AddressObjectType |
128-bit address of the intended recipient of the packet. |
