What Is My IP Address?
Your public IP address, ISP, location, and connection details. Detected instantly via Cloudflare's global network.
Understanding Your IP Address
Your IP address is the unique identifier your Internet Service Provider (ISP) assigns to your connection. Every device connected to the internet has one, and it is visible to every website and service you access.
There are two types of IP addresses: public and private. Your public IP is what the outside world sees. It is assigned by your ISP and shared by all devices on your home network. Private IPs (like 192.168.x.x or 10.x.x.x) are used internally by your router to identify individual devices on your local network.
The tool above shows your public IP address, detected at the network edge via Cloudflare. It also identifies your ISP, approximate location, ASN (Autonomous System Number), and whether you are on IPv4 or IPv6.
IPv4 vs IPv6
IPv4 addresses use 32 bits (e.g., 192.168.1.1), providing about 4.3 billion unique addresses. IPv6 uses 128 bits (e.g., 2001:db8::1), offering virtually unlimited addresses. Most networks run both protocols simultaneously (dual-stack).
Static vs Dynamic IP
Most home connections use dynamic IPs that change periodically. Business connections often use static IPs that remain fixed. Check if your IP changes by bookmarking this page and comparing over time.
Your IP Address and Privacy
Your IP address reveals more than you might think. Websites can see your approximate city, your ISP, and whether you are using a residential or commercial connection. This information is used for content localization, fraud prevention, and targeted advertising.
However, your IP address does not reveal your exact street address, name, or other personal details. Only your ISP can link your IP to your identity, and they are legally required to protect that information.
If you want to mask your public IP, you can use a VPN (Virtual Private Network), which routes your traffic through a server in another location. This replaces your real IP with the VPN server's IP address.
Common Uses for IP Lookup
Troubleshooting
Verify your public IP when setting up port forwarding, remote access, or firewall rules. Confirm your ISP is assigning the correct address.
VPN Verification
Check that your VPN is working by confirming your IP address shows the VPN server's location instead of your actual location.
Security Checks
Identify your connection type, ASN, and ISP. Useful for verifying that your traffic is routing through the expected network.

Frequently Asked Questions
What is an IP address?
An IP (Internet Protocol) address is a unique numerical label assigned to every device connected to the internet. It serves two purposes: identifying your device on the network and providing your approximate geographic location. There are two versions: IPv4 (like 192.168.1.1) and IPv6 (like 2001:0db8:85a3::8a2e:0370:7334).
Is my IP address public?
Yes. Your public IP address is visible to every website and service you connect to. It is how the internet routes data back to your device. Your ISP assigns this address to your connection. If you want to hide your public IP, you can use a VPN (Virtual Private Network) to mask it.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (about 4.3 billion possible addresses) in a dotted decimal format like 192.168.1.1. IPv6 uses 128-bit addresses (virtually unlimited) in a hexadecimal format like 2001:db8::1. IPv6 was created because the world ran out of IPv4 addresses. Most modern networks support both.
Can someone find my exact location from my IP address?
No. An IP address typically reveals your city or metro area and your ISP, but not your exact street address or home location. IP geolocation is approximate, often accurate to the city level but sometimes only to the region or country. Only your ISP can link your IP to your exact address, and they are legally required to protect that information.
What is an ASN?
An ASN (Autonomous System Number) is a unique identifier assigned to a network operator like an ISP, cloud provider, or large organization. For example, Comcast is AS7922 and Google is AS15169. ASNs are used in BGP (Border Gateway Protocol) routing to direct internet traffic between networks.
Why does my IP address change?
Most residential ISPs assign dynamic IP addresses that can change periodically, typically when your router restarts or your DHCP lease expires. This is normal. If you need a fixed IP, you can request a static IP from your ISP (usually for an additional fee). Business plans often include static IPs by default.
