Table 2: IPv6 Header Field Descriptions
Field Description
Version 4-bit Internet Protocol version number = 6.
Prio. 4-bit priority value.
Flow Label 24-bit flow label.
Payload Length 16-bit unsigned integer. The length of payload, for example, the rest of the packet
following the IPv6 header, in octets. If the value is zero, the payload length is
carried in a jumbo payload hop-by-hop option.
Next Header 8-bit selector. Identifies the type of header immediately following the IPv6 header.
This field uses the same values as the IPv4 protocol field.
Hop Limit 8-bit unsigned integer. Decremented by 1 by each node that forwards the packet.
The packet is discarded if the hop limit is decremented to zero.
Source Address 128-bit address of the originator of the packet.
Destination Address 128-bit address of the intended recipient of the packet (possibly not the ultimate
recipient if a routing header is present).
