IP Address Lookup — What Is My IP Address?

Every device connected to the internet is assigned a unique identifier called an IP address (Internet Protocol address). When you visit a website, stream a video, or send an email, your IP address is used to route data back to your device. This tool instantly shows your public IP address — the address that the rest of the internet sees — along with detailed geolocation information including your city, region, country, Internet Service Provider (ISP), timezone, and geographic coordinates.

How to Use the IP Address Lookup Tool

Simply open this page and your IP address is detected automatically. No buttons to click, no forms to fill out. Your public IP address is displayed prominently along with six detail cards showing your location and network information. Click the copy button next to your IP address to instantly copy it to your clipboard. This tool works on any device with a web browser — desktop, tablet, or mobile.

Understanding Your IP Address

There are two versions of IP addresses in use today. IPv4 addresses are the most common and look like four numbers separated by dots (e.g., 192.168.1.1). IPv6 addresses are newer and use hexadecimal characters separated by colons (e.g., 2001:0db8:85a3::8a2e:0370:7334). Your ISP assigns your public IP address, which can be either static (permanent) or dynamic (changes periodically). Most home internet connections use dynamic IP addresses.

Why Would You Need to Know Your IP Address?

Knowing your IP address is useful in many situations: setting up remote access to your computer or home network, troubleshooting network connectivity issues, configuring server access lists, verifying that your VPN is working correctly, diagnosing website geo-blocking, or simply understanding what information websites can see about your connection. Security professionals also use IP lookups to investigate suspicious network activity.

Frequently Asked Questions

An IP address (Internet Protocol address) is a unique numerical identifier assigned to every device connected to a network that uses the Internet Protocol for communication. It serves two main functions: identifying the host or network interface, and providing the location of the device in the network. IPv4 addresses look like 192.168.1.1, while IPv6 addresses are longer hexadecimal strings.
A public IP address is assigned by your Internet Service Provider (ISP) and is visible to the outside world. It is the address that websites and online services see when you connect to them. A private IP address is assigned by your router to devices within your local network (such as 192.168.x.x or 10.x.x.x) and is not accessible from the internet. This tool shows your public IP address.
IP geolocation is generally accurate at the city or regional level, but it is not precise enough to pinpoint an exact street address. Accuracy depends on the database used and how your ISP routes traffic. Typically, the country and region are correct over 99% of the time, while city-level accuracy is around 80-90%. IP geolocation should not be used for exact location tracking.
Your IP address can reveal your general geographic area (city or region) and your ISP, but it cannot identify you personally or provide your exact address. Law enforcement can request ISP records with a legal warrant. To protect your privacy, you can use a VPN (Virtual Private Network) which masks your real IP address with one from a different location.
