Hi;<br />
Following script lists all possible ip address in range:<br />
<br />

<pre><code id="code-20-37839300-1">#!/bin/bash

is_alive_ping()
{
  ping -c 1 $1 &gt; /dev/null
  [ $? -eq 0 ] &amp;&amp; echo Node with IP: $i is up.
}

for i in 192.168.1.{1..255} 
do
is_alive_ping $i &amp; disown
done</code></pre>
<br />
Then save the scipt as a named bash_ping_scan.sh<br />
<br />
Execute the script file 
<pre><code id="code-20-37839300-2">./bash_ping_scan.sh</code></pre>
<br />
Sample output like this:<br />
<br />

<pre><code id="code-20-37839300-3">Node with IP: 192.168.1.1 is up.
Node with IP: 192.168.1.4 is up.

Hi;
Following script lists all possible ip address in range:



#!/bin/bash

is_alive_ping()
{

  [ $? -eq 0 ] && echo Node with IP: $i is up.
}

for i in 192.168.1.{1..255} 
do
is_alive_ping $i & disown
done


Then save the scipt as a named bash_ping_scan.sh

Execute the script file

./bash_ping_scan.sh


Sample output like this:

Hello , <br />
<br />
i need to write small bash script to list in loop all possible ip addresses in specific subnet or ip block. <br />
<br />
example 1 : <br />
ip block 192.168.1.0/24 will list : <br />
192.168.1.1 - 192.168.1.254<br />
<br />
example2: <br />
192.168.1.96/27<br />
will list the following ip addresses : <br />
192.168.1.97 - 192.168.1.126<br />
<br />
exmple 3: <br />
172.16.0.0 / 20<br />
will list the following ip addresses : <br />
172.16.0.1 - 172.16.15.254<br />
<br />
thank you !

How to List all ip addresses on ip block or subnet !?

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.

Linux Networking

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.
