IP Address Tracker with React and Vite

It was really challenging and at the same time fulfilling. Uhm, some of the challenges I faced while coding are:

1. Geolocation-db.com API (used to get user IP) returning crazy IP at times.
2. React-leaflet map failing to work due to problem with CSS height property(took me a long time and a lot of googling to figure out).
3. React-leaflet marker image not showing and at times pointing to wrong position (I did try my best to fix it with answers found on stackoverflow).
4. fetch API returns CORS error most times (Axios fixed it but I don't know why axios would work and fetch wouldn't).
5. Package.json showing error with no fault (a quick stroll through stackoverflow fixed it - Restart VSCode. Voila!).
6. Images on the page not showing on production build and deployment to Netlify server (Happens that I was the one making the mistake all along - I spent all evening on this).

Well, I have a ton of things to write but that's all for now.

I will really like your suggestions on ways I can improve the code for faster and better performance
