What Is My IP Address

An IP address (Internet Protocol address) is a unique string of numbers separated by periods (IPv4) or colons (IPv6) that identifies each device using the Internet Protocol to communicate over a network. Every device that connects to the internet — whether it's a smartphone, laptop, or smart TV — is assigned an IP address by its network.

There are two main versions of IP addresses in use today. IPv4 addresses look like 192.168.1.1 and are the most common format. IPv6 addresses are longer and were created to handle the growing number of devices online.

Why Your IP Address Matters

Your IP address is essential for online communication. Without it, websites wouldn't know where to send the data you request. When you visit a website, your browser sends your IP address to the server so it can send the webpage back to you.

However, your IP address also reveals information about you. It can show your approximate geographic location, your Internet Service Provider (ISP), and can be used by websites for analytics, personalization, and sometimes geo-restrictions. This is why many privacy-conscious users choose to use a VPN to mask their real IP address. Learn more in our Privacy & VPN guide.
