What is my IP address

What is an IP address

An IP address is a unique identifier assigned to every device connected to the internet. It allows servers and websites to send data back to your device when you visit a website or use an online service.

Your public IP address is visible to websites and online services you connect to. It can reveal your approximate geographic location and the internet provider used for the connection.

There are two main versions of IP addresses used today: IPv4 and IPv6. IPv4 addresses consist of four numbers separated by dots, while IPv6 addresses use a longer hexadecimal format.

How to find your public IP

Your public IP address can be detected automatically when you visit a website. Services like iptest.pro display your IP address instantly together with basic location information.

You can also check your IP address directly from the command line:

curl iptest.pro

Why your IP address matters

Your IP address is used for routing traffic across the internet. It is also used by websites for security checks, localization, analytics and access control.

If you use a VPN, proxy or different network, your visible public IP address may change. That is why IP check tools are useful for verifying whether your connection appears the way you expect.

IPv4 vs IPv6

IPv4 is still the most widely used address format on the internet, but IPv6 adoption continues to grow. Some users will only see IPv4, while others may see IPv6 depending on their ISP, router and network configuration.

iptest.pro helps you quickly determine which IP version is currently visible to websites and services.
