An IP address is a unique set of numbers assigned to each Internet or network device. It allows devices on a network to communicate with each other by assigning them a unique number known as an IP address. 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. It is assigned by your internet service provider (ISP) and is used by devices connected to the internet to communicate with each other across the web. A private IP address is an internal network address that allows connected devices within a network to communicate with one another. It is used by routers and modems for local area networks (LANs) .

To find out what your public IP address is, you can visit websites such as https://whatismyipaddress.com, https://www.whatismyip.com, https://nordvpn.com/what-is-my-ip/, or https://www.showmyip.com. These websites will display your public IPv4 and IPv6 address, as well as additional information such as your IP location, city, region, country, ISP, and user agent.
