What's the Real Difference Between Private vs Public IP Addresses? or Private vs Public IP Addresses:

Short answer: Public IP = your face on social media. Private IP = your DMs.

Longer: Public ips are for the whole internet to see (like your router’s WAN address). Private ips are for your LAN—phones, laptops, etc. They’re reused in every home network cuz why waste unique public ones?

Tools? Cmd prompt > `ipconfig` (Windows) or `ifconfig` (Mac/Linux) to see your private IP.
