FastAPI with a HTML and JavaScript Front End | IP Subnet Overlap Checker

Full project with a HTML/JavaScript front end to call the API I have written using FastAPI and Python to check for overlapping ip subnets. The core concepts of linking the parts together is the theme of the video rather than any in depth network details.
I show the code working and highlight noteworthy aspects of the project.

Proxies
=================================================
If you need a good, easy to use proxy, I was recommended this one, and having used ScraperAPI for a while I can vouch for them. If you were going to sign up anyway, then maybe you would be kind enough to use the link and the coupon code below?

You can also do a full working trial first as well, (unlike some other companies). The trial doesn't ask for any payment details either so all good! ?
