About

Simple program to check if IP addresses are active or not using ping command.

How it works

It simply pings a website (of your choice) and depending on the status code returned by the ping command, it determines the status of the website or IP address.

Possible statuses are:

• 0 => Alive
• 1 or 256 => Unreachable
• 2 or 68 => Unknown host
• [Any other code] => Unknown

Supported Operating Systems

• Windows
• Linux
• Android (via Native Linux Terminal, not tested yet)

General Requirements

• Internet connection

Installation

On Windows

Open PowerShell with Admin privileges and run this command:

Set-ExecutionPolicy RemoteSigned; Invoke-WebRequest https://raw.githubusercontent.com/1ray-1/check-ip/main/install-windows.ps1 -OutFile "$PWD\install-windows.ps1";  .\install-windows.ps1

After that, unless you really need to execute other PowerShell scripts, I recommend disabling script execution for better security

Set-ExecutionPolicy Restricted

On Linux

Open terminal and run this command:

wget https://raw.githubusercontent.com/1ray-1/check-ip/main/install-linux.sh; chmod +x install-linux.sh; clear; bash install-linux.sh

You'll need to enter your sudo password

In both cases (Linux and Windows), the required executable (for your system architecture) will be installed in a directory that's in your PATH, so you can run it by simply typing check-ip in the terminal or CMD

From releases

You can just download the executable file for your OS here and execute it.

From source

You can download this repo and compile check-ip.c manually (using C compiler).

How to use (from CMD/Terminal)

Usage: check-ip [OPTION] IP_ADDRESSES_TO_CHECK

Options:
-s            Save data to data.txt
-h, --help    Get help text

How to remove

On Windows

Open CMD with admin privileges and type:

• del C:\Windows\System32\check-ip.exe

On Linux

Open terminal and type:

• sudo rm $(which check-ip)

Note: I'm not a C programmer. The code is simple and could be improved, but it works.
