What is an IP address?
An IP address, or Internet Protocol address, is a unique address that identifies a device on a network. This address allows devices to communicate with each other over the internet or within a local network. Just like your home has a unique postal address for mail delivery, each device connected to the internet requires an IP address to send and receive information.
IP addresses can be classified into two types: IPv4 and IPv6. IPv4 addresses are numeric and consist of four sets of digits separated by periods, while IPv6 addresses are alphanumeric and designed to accommodate the increasing number of devices connected to the internet. Understanding your device’s IP address is essential for various tasks, such as troubleshooting network issues or configuring network settings.
