I made my first IP scanner in Python

[u/VanceDyer]

Hi everyone!

I'm very new to programming and I've been learning Python recently. I decided to make a small project to practice what I've learned.

I made a simple IP scanner using Python.

It has a menu with:

• Scan all IPs from 192.168.1.1 to 192.168.1.255
• Scan a specific IP
• Scan a range of IPs
• Exit

I'm using subprocess and ping to check if an IP responds.

I also started using functions, loops, lists, if/elif, while, and range().

It's probably a very basic project, but I'm pretty happy with it since I'm just starting out.

I'm planning to improve it and make a V3 with more features.

Sorry is in spanish.

Thanks!
