What is an IP address?
An IP address, or Internet Protocol address, is a unique identifier assigned to every device connected to a network. It enables devices to communicate with each other by serving as their return address, much like how a postal address works in the physical world. It helps in locating devices on the network and facilitating data transfer across the internet.
There are two main types of IP addresses: IPv4 and IPv6. IPv4 addresses are made up of four sets of numbers ranging from 0 to 255, separated by periods (e.g., 192.168.1.1). IPv6 addresses, on the other hand, are represented in hexadecimal format and can accommodate a much larger number of devices. Understanding your device’s IP address is crucial for troubleshooting network issues and configuring network settings.
