What is IP address?

An IP address helps computers, phones, and other devices identify each other on a network. When you visit a website, send an email, or stream a video, your device uses IP addresses to find the right place to send and receive data.

There are two common types: public IP addresses, which identify your network on the internet, and private IP addresses, which identify devices inside your home or office network. Your internet provider usually assigns your public IP address, while your router gives private IP addresses to devices on your Wi-Fi.

IP addresses matter because without them, devices would not know where to deliver information. They make everyday online activities like browsing, video calls, and app updates possible.
