What Is My IP Address?

An IP address (Internet Protocol Address) is a unique numerical identifier assigned to every device connected to a network that uses the Internet Protocol. Whether you're browsing websites, streaming videos, sending emails, playing online games, or using cloud services, your device relies on an IP address to communicate with servers and other devices across the internet.

You can think of an IP address as the internet equivalent of a mailing address. Just as a postal service needs your home address to deliver a package, websites and online services need your IP address to send data back to your device. Without an IP address, your computer, smartphone, tablet, or other connected device would not be able to access websites or communicate over the internet.

This free IP Address Lookup tool instantly detects your current public IP address and displays additional network information including your Internet Service Provider (ISP), hostname, Autonomous System Number (ASN), approximate geographic location, timezone, and whether you're using an IPv4 or IPv6 address.

Your IP address is assigned by your Internet Service Provider whenever you connect to the internet. Depending on your provider and network configuration, the address may remain the same for long periods or change automatically over time. Most residential internet connections use dynamic IP addresses, while businesses and servers often use static IP addresses for consistent connectivity.

Because every internet-connected device requires an IP address, checking your current IP can be useful for troubleshooting network problems, configuring routers, testing VPN connections, accessing remote services, diagnosing connectivity issues, verifying firewall settings, or simply confirming how your internet connection appears to websites.

There are two main types of IP addresses: public and private. Your public IP address is assigned by your Internet Service Provider and is visible to websites and online services. This is the address displayed by this tool.

Private IP addresses are used only inside your local network. Your home router typically assigns private IP addresses to devices such as laptops, smartphones, printers, gaming consoles, and smart TVs. These addresses cannot be accessed directly from the internet and help organize devices within your local network.

When you visit a website, your router translates your private IP into your public IP using Network Address Translation (NAT). This allows multiple devices in your home or office to share a single public IP address while remaining protected from direct internet access.

Internet Protocol currently exists in two primary versions: IPv4 and IPv6. Both perform the same fundamental function of identifying devices on networks, but they differ in address format and capacity.

IPv4 uses a 32-bit address format, producing addresses like 192.168.1.1. While IPv4 has powered the internet for decades, its address pool is limited to approximately 4.3 billion unique addresses.

IPv6 was introduced to solve IPv4 address exhaustion. It uses a 128-bit address format, allowing an almost unlimited number of unique addresses. IPv6 addresses appear much longer and contain hexadecimal characters, for example: 2001:0db8:85a3::8a2e:0370:7334.

Today many internet providers support both IPv4 and IPv6 simultaneously. This tool automatically checks both versions whenever they are available on your network.

If you're connected through a VPN, proxy server, or a corporate network, the public IP address displayed by this tool may belong to the VPN provider, proxy service, or organization instead of your home internet connection. This is completely normal because your internet traffic is routed through another server before reaching websites.

Many people use this tool to verify that their VPN is working correctly. After connecting to a VPN, refreshing the page should display a different public IP address, allowing you to confirm that your internet traffic is being routed through the selected VPN server.

Proxy servers operate in a similar way by masking your original public IP address. Whether you're using a VPN, proxy, or business network, this tool helps you quickly identify the IP address currently visible to websites and online services.
