инструмент генерации сетевых пакетов / утилита ping (Network packet generation tool / ping utility)
OPTION SPECIFICATION
Nping is designed to be very flexible and fit a wide variety of
needs. As with most command-line tools, its behavior can be
adjusted using command-line options. These general principles
apply to option arguments, unless stated otherwise.
Options that take integer numbers can accept values specified in
decimal, octal or hexadecimal base. When a number starts with 0x,
it will be treated as hexadecimal; when it simply starts with 0,
it will be treated as octal. Otherwise, Nping will assume the
number has been specified in base 10. Virtually all numbers that
can be supplied from the command line are unsigned so, as a
general rule, the minimum value is zero. Users may also specify
the word random or rand to make Nping generate a random value
within the expected range.
IP addresses may be given as IPv4 addresses (e.g. 192.168.1.1),
IPv6 addresses (e.g. 2001:db8:85a3::8e4c:760:7146), or
hostnames, which will be resolved using the default DNS server
configured in the host system.
Options that take MAC addresses accept the usual colon-separated
6 hex byte format (e.g. 00:50:56:d4:01:98). Hyphens may also be
used instead of colons (e.g. 00-50-56-c0-00-08). The special
word random or rand sets a random address and the word broadcast
or bcast sets ff:ff:ff:ff:ff:ff.
