Port Scanner

This is a simple Python script for scanning ports on a target machine using multithreading. It utilizes the socket library for establishing connections to ports and threading for concurrent scanning of multiple ports.

Overview

This script allows users to specify a target IP address (or localhost) and range of ports to scan. It then checks each port within the specified range for openness by attempting to establish a TCP connection. If the connection is successful (connect_ex returns 0), the port is considered open, otherwise, it's marked as closed.

Features

• Multithreaded Scanning: The script uses threading to scan multiple ports concurrently, which can significantly reduce scanning time, especially when scanning a wide range of ports.

• Customizable Port Range: Users can specify the range of ports to scan, allowing flexibility based on their requirements.

• Real-time Feedback: The script provides real-time feedback on whether each scanned port is open or closed, making it easy to monitor the progress of the scan.

• DNS: Now with domain name resolution!

How to Use

1. Clone the Repository: Clone or download the repository containing the script.

2. Install Python: Make sure you have Python installed on your system. The script is compatible with Python 3.

3. Run the Script: Execute the script using Python from the command line. Provide the target IP address or localhost when prompted, and optionally specify the range of ports to scan.
