What is an IP Address?
An IP address (Internet Protocol address) is a unique numeric label assigned to every device connected to the internet. It works like a mailing address for your device, allowing websites and online services to know where to send the data you request.
There are two versions in use today. IPv4 addresses look like 203.0.113.42 — four numbers separated by dots. Because the world ran out of IPv4 addresses, IPv6 was introduced; these are longer, such as 2001:0db8:85a3::8a2e:0370:7334.
The address shown above is your public IP address — the one the wider internet sees. It is assigned by your Internet Service Provider (ISP) or mobile carrier, and it is usually shared by every device on your home or office network. This is different from your private IP address (like 192.168.x.x), which only identifies your device inside your local network.
This tool detects your IP on the server side, which means it reports the real address your connection is coming from even when this website is served through Cloudflare or another reverse proxy.
How to Use the IP Address Checker
There is nothing to configure — your public IP is detected automatically the moment the page loads:
- Open the tool – your public IP address is shown immediately at the top of the page.
- Check the IP version – the tool tells you whether you are connecting over IPv4 or IPv6.
- Review connection details – see whether your IP was detected through a proxy (such as Cloudflare) and which browser/user agent you are using.
- Copy the address – click "Copy IP" to put your IP on the clipboard for support tickets, allowlists, or firewall rules.
- Refresh – click "Refresh" to re-check, which is handy after connecting or disconnecting a VPN.
How We Detect Your Real IP Behind Cloudflare
When a website sits behind Cloudflare or a reverse proxy, the web server normally only sees the proxy's IP address, not yours. A naive IP checker would simply report Cloudflare's server IP — which is the wrong answer.
To show your true address, this tool inspects the proxy headers in a specific order of trust:
CF-Connecting-IP– Cloudflare's dedicated header containing the original visitor IP.True-Client-IP– used by Cloudflare Enterprise and some CDNs such as Akamai.X-Forwarded-For– a standard proxy header; we take the left-most (original client) entry.X-Real-IP– commonly set by nginx and other reverse proxies.- The direct connection IP – used only as a final fallback when no proxy headers are present.
Every candidate value is validated as a real IPv4 or IPv6 address before it is displayed, so a malformed or spoofed header can never be shown as your IP.
Common Reasons to Check Your IP Address
-
✓
VPN & proxy testing: confirm your IP actually changes after connecting to a VPN, and check whether your real IP is leaking.
-
✓
Allowlisting & firewalls: quickly grab the IP you need to add to a server allowlist, database access rule, or office firewall.
-
✓
Technical support: support teams often ask for your public IP to diagnose connectivity or access problems.
-
✓
IPv6 readiness: check whether your ISP has given you an IPv6 address yet.
-
✓
Web development: developers building behind Cloudflare can verify that the real client IP is being forwarded correctly.
Privacy & Important Notes
We do not store your IP. Your IP address is detected to display it back to you and is not logged or shared by this tool.
Public vs private: the address shown is your public, internet-facing IP. Devices on your local network share this same public IP.
Dynamic addresses: most home connections use dynamic IPs that change periodically, so the value here may differ next time you visit.
VPN consideration: if you are on a VPN, the IP shown is the VPN exit node's address, not your home IP.
Frequently Asked Questions (FAQ)
What is the difference between a public and private IP address?
Your public IP is the address the internet sees and is assigned by your ISP. Your private IP (such as 192.168.1.5) is used only inside your home or office network. This tool shows your public IP.
How do you get my real IP if the site is behind Cloudflare?
Cloudflare passes your original IP to the server in the CF-Connecting-IP header. We read that header (and fall back to True-Client-IP, X-Forwarded-For, and X-Real-IP), validate it as a real IP, and display it — so you see your address rather than Cloudflare's.
Why is my IP version IPv6 instead of IPv4?
If your ISP and connection support IPv6, your browser may prefer it. IPv6 is the newer addressing standard that solves the shortage of IPv4 addresses. Seeing an IPv6 address simply means your connection used it for this request.
Does this tool store or track my IP address?
No. Your IP is detected only to show it back to you. The tool does not log or share your IP address.
Why does my IP change from time to time?
Most consumer ISPs assign dynamic IP addresses that can change when your router reconnects or after a lease expires. Connecting to a VPN or mobile network will also change the IP shown here.
Can someone find my location from my IP address?
An IP address can reveal a rough region or city and your ISP, but not your exact home address. Only your ISP can link an IP to a specific account.
