What's 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.
How It Works
You Connect
When you visit this page, your browser connects to Cloudflare's nearest edge server out of 300+ global locations.
We Detect
The edge server reads your IP address, identifies your ISP via BGP routing data, and determines your approximate location.
You See
Your IP details are displayed right in your browser. Nothing is stored, logged, or shared. Your data stays with you.
Frequently Asked Questions
What's my IP address?
Your IP address is a unique number assigned to your device by your ISP whenever you connect to the internet. You can see your current public IP address instantly at the top of this page. It also shows your ISP, approximate location, and whether you are using IPv4 or IPv6.
How do I find my IP address?
The fastest way to find your public IP address is to visit this page. Your IP is detected automatically via Cloudflare's global network. You can also find it by running "curl ifconfig.me" in your terminal, or by checking your router's admin page at 192.168.1.1.
Can someone find my location from my IP?
An IP address reveals your approximate city and ISP, but not your exact street address or personal information. IP geolocation is accurate to the city or metro level. Only your ISP can link your IP to your identity, and they are legally required to protect that data.
How do I hide my IP address?
The most common way to hide your IP address is to use a VPN (Virtual Private Network). A VPN routes your traffic through a server in another location, replacing your real IP with the VPN server's IP. You can verify your VPN is working by checking your IP on this page before and after connecting.
Why does my IP address change?
Most home internet connections use dynamic IP addresses that change periodically. Your ISP assigns a new IP 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 monthly fee.
Is my IP the same on all my devices?
All devices on the same Wi-Fi network share the same public IP address. Each device has a different private IP assigned by your router. If your phone is on cellular data instead of Wi-Fi, it will have a completely different public IP assigned by your mobile carrier.
Do I have IPv6?
This page automatically checks whether your connection supports IPv6. If your ISP and router both support it, you will see your IPv6 address displayed alongside your IPv4 address at the top of this page. If IPv6 shows "Not Available," it means your connection is IPv4-only. Most major ISPs now support IPv6, but availability depends on your specific plan, router configuration, and your ISP's rollout in your area.
