What is an IP Address?
An IP address (Internet Protocol address) is a unique numerical identifier assigned to every device connected to a computer network that uses the Internet Protocol. Think of it as your device's digital mailing address — it tells the internet where to send data like web pages, emails, and video streams.
The most common version is IPv4, a 32-bit address written as four decimal numbers separated by dots (e.g., 192.168.1.1). With the growth of the internet, IPv4 addresses have become scarce, leading to the adoption of IPv6 — a 128-bit hexadecimal format (e.g., 2001:db8::1) that provides an enormous number of unique addresses. Your public IP address is the one assigned by your internet service provider (ISP) and visible to the websites you visit.
What is a User Agent?
A user agent is a string of text that your browser sends to every website you visit, identifying your browser type, version, operating system, and device information. Websites use this data to optimize the content they deliver — for example, showing a mobile-friendly layout to phone users or offering the correct file format for downloads.
Frequently Asked Questions
What is the difference between a public and private IP address?
A public IP address is assigned by your ISP and is visible to the internet. A private IP address is used within your local network. This tool shows your public IP address.
Can someone find my exact location from my IP address?
No. IP geolocation is not precise enough to pinpoint your exact physical address. It typically provides the general area (city or region) of your ISP's infrastructure.
What is Proxy/VPN detection?
The "Proxy / VPN" indicator shows whether the IP address is likely from a proxy server, VPN service, or anonymizer. This is useful for security screening and detecting fraudulent traffic.
