Целевая спецификация (Target specification)

Everything on the Nping command line that isn't an option or an
       option argument is treated as a target host specification. Nping
       uses the same syntax for target specifications that Nmap does.
       The simplest case is a single target given by IP address or
       hostname.

       Nping supports CIDR-style addressing. You can append /numbits to
       an IPv4 address or hostname and Nping will send probes to every
       IP address for which the first numbits are the same as for the
       reference IP or hostname given. For example, 192.168.10.0/24
       would send probes to the 256 hosts between 192.168.10.0 (binary:
       11000000 10101000 00001010 00000000) and 192.168.10.255 (binary:
       11000000 10101000 00001010 11111111), inclusive.
       192.168.10.40/24 would ping exactly the same targets. Given that
       the host scanme.nmap.org is at the IP address 64.13.134.52, the
       specification scanme.nmap.org/16 would send probes to the 65,536
       IP addresses between 64.13.0.0 and 64.13.255.255. The smallest
       allowed value is /0, which targets the whole Internet. The
       largest value is /32, which targets just the named host or IP
       address because all address bits are fixed.

       CIDR notation is short but not always flexible enough. For
       example, you might want to send probes to 192.168.0.0/16 but skip
       any IPs ending with .0 or .255 because they may be used as subnet
       network and broadcast addresses. Nping supports this through
       octet range addressing. Rather than specify a normal IP address,
       you can specify a comma-separated list of numbers or ranges for
       each octet. For example, 192.168.0-255.1-254 will skip all
       addresses in the range that end in .0 or .255, and
       192.168.3-5,7.1 will target the four addresses 192.168.3.1,
       192.168.4.1, 192.168.5.1, and 192.168.7.1. Either side of a range
       may be omitted; the default values are 0 on the left and 255 on
       the right. Using - by itself is the same as 0-255, but remember
       to use 0- in the first octet so the target specification doesn't
       look like a command-line option. Ranges need not be limited to
       the final octets: the specifier 0-.-.13.37 will send probes to
       all IP addresses on the Internet ending in .13.37. This sort of
       broad sampling can be useful for Internet surveys and research.

       IPv6 addresses can only be specified by their fully qualified
       IPv6 address or hostname. CIDR and octet ranges aren't supported
       for IPv6 because they are rarely useful.

       Nping accepts multiple host specifications on the command line,
       and they don't need to be the same type. The command nping
       scanme.nmap.org 192.168.0.0/8 10.0.0,1,3-7.- does what you would
       expect.
