What is an IP Address Lookup?
The IP Address Lookup tool is a free online utility that instantly identifies your public IP address, geolocation (country/region/city), and ISP (Internet Service Provider) information. It auto-detects upon page load — no input required.
It also supports custom IP/domain lookups, IPv6 detection, VPN/proxy detection, and reverse DNS lookups for advanced network diagnostics. Your approximate location is displayed visually on a map for quick reference.
Key Features
Auto IP Detection & Copy
Automatically detects your public IP address when you visit the page and lets you copy it to your clipboard with one click.
Geolocation & Map Display
Identifies your country, region, city, and coordinates based on IP and displays your approximate location visually on a map.
VPN/Proxy & IPv6 Detection
Automatically detects VPN or proxy usage and also checks for IPv6 address availability alongside your IPv4 address.
Custom IP/Domain Lookup
Look up any IP address or domain name to retrieve its geolocation, ISP, and network information beyond just your own IP.
How to Use
- Visit the Page — Your public IP address and location information are automatically detected when you load the page.
- Check IP Address — Your current public IP address is displayed prominently at the top. Click the copy button to copy it.
- View Location & Network Info — Check your approximate location (country, region, city) along with ISP and VPN detection results.

Use Cases
Security Check
Verify your current IP to ensure you're not connecting from an unintended location or network.
VPN Verification
Confirm that your VPN is working correctly by checking whether your IP address and location have actually changed after connecting.
Network Diagnostics
Check ISP information, AS numbers, and reverse DNS to help diagnose network issues and connectivity problems.
Server & Remote Management
Quickly identify your current IP address to add it to server firewall allowlists or remote access configurations.
Frequently Asked Questions
What is my IP address?
An IP address (Internet Protocol Address) is a unique numerical address assigned to every device connected to the internet. It enables data to be sent and received across the network.
Is the location shown accurate?
IP-based geolocation can determine your approximate location (city level). It may differ from your exact street address or GPS coordinates, and may show your ISP's server location instead.
Does using a VPN change my IP?
Yes, when using a VPN, the VPN server's IP address is displayed instead of your real one. This hides your actual IP and location.
What is the difference between IPv4 and IPv6?
IPv4 uses 32-bit addresses (e.g., 192.168.0.1) providing about 4.3 billion addresses. IPv6 uses 128-bit addresses (e.g., 2001:0db8::1) providing virtually unlimited addresses.
Can I check my IP address on a smartphone?
Yes! Just open this page in your mobile browser. On Wi-Fi, your router's public IP is displayed. On LTE/5G, the public IP assigned by your carrier is shown.
What is the difference between a public IP and a private IP?
A public IP is your internet-facing address assigned by your ISP, visible globally — this is what this tool shows. A private IP (e.g., 192.168.x.x) is used only within your local network and is not visible on the internet.
Privacy Notice
While external APIs (ip-api.com, ipify.org) are called to look up IP information, the results are only displayed in your browser and are not stored on any server. All lookup data disappears when you close the page.
