Destination Prefix-Length – A decimal value indicating how many
◆
contiguous bits (from the left) of the address comprise the prefix; i.e.,
the network portion of the address. (Range: 0-8 bits)
DSCP – DSCP traffic class. (Range: 0-63)
◆
Next Header – Identifies the type of header immediately following the
◆
IPv6 header. (Range: 0-255)
Optional internet-layer information is encoded in separate headers that
may be placed between the IPv6 header and the upper-layer header in
a packet. There are a small number of such extension headers, each
identified by a distinct Next Header value. IPv6 supports the values
defined for the IPv4 Protocol field in RFC 1700, and includes these
commonly used headers:
0 : Hop-by-Hop Options (RFC 2460)
6 : TCP Upper-layer Header (RFC 1700)
17 : UDP Upper-layer Header (RFC 1700)
43 : Routing (RFC 2460)
44 : Fragment (RFC 2460)
50 : Encapsulating Security Payload (RFC 2406)
51 : Authentication (RFC 2402)
60 : Destination Options (RFC 2460)
