Simple Python Port Scanner

This is my updated Python port scanner script. It scans specified IP addresses for open TCP ports using multithreading to speed up the process.

🚧 Note:
This version improves on the first by allowing multiple IPs to be scanned, supports user-defined port ranges, and validates IP addresses before scanning.

Features in this version:

• Scan multiple IP addresses in one run
• Validate IP addresses before scanning
• Specify start and end ports for scanning
• Use multithreading for faster scanning
• Timeout settings for quicker responses

🎯 Goal:
Keep learning Python networking and improve the tool gradually.
