Basic Command Prompt For Looping To Find Live IP Address

Actually there is many ways to do looping the
program in command prompt, but for today we will
focus on FOR looping.
According to wikipedia
In computer science a for loop is a programming
language statement which allows code to be
repeatedly executed. A for loop is classified as an
iteration statement.
Unlike many other kinds of loops, such as the
while loop, the for loop is often distinguished by
an explicit loop counter or loop variable. This
allows the body of the for loop (the code that is
being repeatedly executed) to know about the
sequencing of each iteration. For loops are also
typically used when the amount of iterations is
known before entering the loop. For loops are the
shorthand way to make loops when the number of
iterations is known, as a for loop can be written as
a while loop.
Requirement:
1. Command Prompt
Step by step Basic Command Prompt For Looping
to Find Live IP Address:
1. If you already understand about basic FOR looping
in programming, I believe this tips and trick should
be easy for you.
Open your command prompt (Windows keyboard +
R and type cmd).
2. Firstly, the most important one is reading the
manual. We can see the help by typing help for to
view the manuals.
3. My computer was resides on 192.168.8.0/24
network. We will try to scan the live IP address on
this network using command prompt FOR looping.
Here is my command
for /L %h IN (87,1,99) DO ping 192.168.8.%h -l 1 -n
1
Information:
for /L %h –> perform a command for a range of
numbers where %h is the variable
IN (87, 1, 99) –> start looping from 87 with step
amount 1 until 99
DO ping 192.168.8.%h -l 1 -n 1 –> do the ping to
specified IP address. We only send 1 byte buffer
size(-l 1) and 1 times echo request(-n 1).
Here is the result (I snip some information and show
some live IP address).
Conclusion:
1. This method will work if the target IP not blocking
the ICMP request.
2. To save the result to .txt file you can add >>
result.txt
