IPV6 OPTIONS
-6, --ipv6 (Use IPv6)
Tells Nping to use IP version 6 instead of the default IPv4.
It is generally a good idea to specify this option as early
as possible in the command line so Nping can parse it soon
and know in advance that the rest of the parameters refer to
IPv6. The command syntax is the same as usual except that you
also add the -6 option. Of course, you must use IPv6 syntax
if you specify an address rather than a hostname. An address
might look like 3ffe:7501:4819:2000:210:f3ff:fe03:14d0, so
hostnames are recommended.
While IPv6 hasn't exactly taken the world by storm, it gets
significant use in some (usually Asian) countries and most
modern operating systems support it. To use Nping with IPv6,
both the source and target of your packets must be configured
for IPv6. If your ISP (like most of them) does not allocate
IPv6 addresses to you, free tunnel brokers are widely
available and work fine with Nping. You can use the free IPv6
tunnel broker service at http://www.tunnelbroker.net
Please note that IPv6 support is still highly experimental
and many modes and options may not work with it.
-S addr, --source-ip addr (Source IP Address)
Sets the source IP address. This option lets you specify a
custom IP address to be used as source IP address in sent
packets. This allows spoofing the sender of the packets.
addr can be an IPv6 address or a hostname.
--dest-ip addr (Destination IP Address)
Adds a target to Nping's target list. This option is provided
for consistency but its use is deprecated in favor of plain
target specifications. See the section called 'TARGET
SPECIFICATION'.
--flow label (Flow Label)
Sets the IPv6 Flow Label. The Flow Label field is 20 bits
long and is intended to provide certain quality-of-service
properties for real-time datagram delivery. However, it has
not been widely adopted, and not all routers or endpoints
support it. Check RFC 2460 for more information. label must
be an integer in the range [0–1048575].
--traffic-class class (Traffic Class)
Sets the IPv6 Traffic Class. This field is similar to the TOS
field in IPv4, and is intended to provide the Differentiated
Services method, enabling scalable service discrimination in
the Internet without the need for per-flow state and
signaling at every hop. Check RFC 2474 for more information.
class must be an integer in the range [0–255].
--hop-limit hops (Hop Limit)
Sets the IPv6 Hop Limit field in sent packets to the given
value. The Hop Limit field specifies how long the datagram is
allowed to exist on the network. It represents the number of
hops a packet can traverse before being dropped. As with the
TTL in IPv4, IPv6 Hop Limit tries to avoid a situation in
which undeliverable datagrams keep being forwarded from one
router to another endlessly. hops must be a number in the
range [0–255].
