PTAXFR - DNS Zone Transfer Testing Tool

ptaxfr is a tool that tests domains for DNS zone transfer.
This tool utilizes threading for fast parallel domain testing.

Installation

pip install ptaxfr

Adding to PATH

If you're unable to invoke the script from your terminal, it's likely because it's not included in your PATH. You can resolve this issue by executing the following commands, depending on the shell you're using:

For Bash Users

echo "export PATH=\"`python3 -m site --user-base`/bin:\$PATH\"" >> ~/.bashrc
source ~/.bashrc

For ZSH Users

echo "export PATH=\"`python3 -m site --user-base`/bin:\$PATH\"" >> ~/.zshrc
source ~/.zshrc
