What is a public IP address?
Your public IP address is the ip address that is visible to other devices that you connect to on the internet. Say you visit WhatIsMyIp.Host – then we can see your public IP address. Typically, if someone talks about an “IP Address” they are referring to your public, not private, IP address.
What is a private IP address?
Your private IP address is the ip address assigned within your internal network. Say you have a router at home that multiple devices (your phone and PC) connect to. The router will then assign each device a private IP address so that the router can distinguish internet traffic going to and from each device. When you visit an external website, the website can only see your public IP address.
