An IP address is a unique set of numbers assigned to each internet or network device, which allows devices to communicate with each other, either on an internal or external computer network. There are two types of IP addresses: public and private. A public IP address is the IP that is logged when you visit websites or use services on the internet, and it is assigned by your internet service provider (ISP) . On the other hand, a private IP address is used on local area networks (LANs) like your home WiFi network, and it is usually 10.x.x.x, 172.x.x.x, or 192.x.x.x.

To find out your public IP address, you can visit websites like whatismyip.com or whatismyipaddress.com, which will display your IPv4 and/or IPv6 assigned by your ISP. Knowing your IP address can be useful for troubleshooting network issues or accessing remote devices.
