What is an IP address?
An IP address, or Internet Protocol address, is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies each computer using the Internet Protocol to communicate over a network. It serves two main functions: identifying the host or network interface and providing the location of the device in the network. This address allows devices to send and receive information across the internet effectively.
There are two types of IP addresses: public and private. A public IP address is assigned to your device by your Internet Service Provider (ISP) and is visible to external networks, while a private IP address is used within your local network—like those assigned to devices connected to your home Wi-Fi. Knowing your IP address can be essential for troubleshooting network issues, configuring routers, or accessing certain online services.
