Let's find all the working ip's in the CIDR range by finding their respective open ports.
git clone https://github.com/hackruler/openip.git
cd openip
bash openip.sh -l <path to cidr file> [options]
After Installation
Make an alias using this-
chmod +x <file path>/openip.sh
Append this command in .zshrc file or .bashrc file
alias openip='bash <path to file>/openip/openip.sh
And then type this command to save...
source ~/.bashrc Or source ~/.zshrc
Then you can use this as...
openip -l <domain file path> [options]
