What Is My IP Address? Free IP Lookup, Geolocation & Privacy Guide

Your IP address is the unique number assigned to your device by your Internet Service Provider (ISP) every time you connect to the internet. It acts as your digital return address, allowing websites and services to send data back to you. FindUtils IP Address Lookup shows your public IP instantly along with 24+ data fields including location, ISP, timezone, and connection details.

Every device connected to the internet has an IP address. When you visit a website, your browser sends your IP along with the request. The website's server uses this address to know where to send the page back. This is how the internet works at its most basic level.

How to Find Your Public IP Address

Step 1: Visit the IP Lookup Tool

Open the FindUtils IP Address Lookup tool. Your public IP address is detected automatically on page load, no clicks needed. You'll see both your IPv6 and IPv4 addresses if your connection supports dual-stack.

Step 2: Review Your IP Details

The tool displays your full geolocation profile: country, city, region, postal code, coordinates, timezone, ISP name, ASN number, and more. All 24 fields are available for free with no signup required.

Step 3: Check for Leaks

If you're using a VPN, verify your IP matches the VPN server's location, not your real location. Use the FindUtils DNS & WebRTC Leak Test to check for DNS and WebRTC leaks that could expose your real IP.

Step 4: Export or Copy

Copy individual fields or export the full result as JSON, CSV, or plain text. Your lookup history is saved locally in your browser for easy reference.

IPv4 vs IPv6: What's the Difference?

IPv4 and IPv6 are two versions of the Internet Protocol that assign addresses to devices. IPv4 uses 32-bit addresses (like 192.168.1.1) with about 4.3 billion possible combinations. IPv6 uses 128-bit addresses (like 2001:0db8:85a3::8a2e:0370:7334) with 340 undecillion possible addresses.

Most modern connections use dual-stack, meaning your device has both an IPv4 and IPv6 address. When you visit a website, your browser typically prefers IPv6 if available. FindUtils shows both addresses: IPv6 loads instantly, and IPv4 appears 1-2 seconds later.

How IP Geolocation Works

IP geolocation determines the approximate physical location of an IP address by mapping it against databases maintained by organizations like regional internet registries (RIRs). When an ISP is assigned a block of IP addresses, that assignment is tied to a geographic region.

Geolocation accuracy varies by level:

• Country level: 99% accurate for most databases
• City level: 80-90% accurate, depends on ISP data quality
• Street level: Not possible from IP alone (GPS or Wi-Fi positioning needed)

FindUtils uses geolocation databases to map IP addresses to locations. The IP Address Lookup tool shows city, region, country, coordinates, timezone, and postal code for any IPv4 or IPv6 address.

What Geolocation Cannot Do

IP geolocation resolves to an approximate area, not a precise location. It cannot reveal your street address, building, or apartment number. The coordinates represent the general center of the IP block's assigned area, which is often the nearest city center or ISP hub.

VPN and proxy users will show the location of the VPN server, not their real physical location. This is by design and is one of the primary reasons people use VPNs.

How to Protect Your IP Address

Your IP address reveals your approximate location, ISP, and can be used to track your online activity across websites. Here are the main ways to protect it:

1. Use a VPN (Virtual Private Network) A VPN encrypts your traffic and routes it through a server in another location. Websites see the VPN server's IP instead of yours. This is the most effective way to hide your IP address.

2. Use Tor Browser Tor routes your traffic through multiple volunteer-run relays, making it extremely difficult to trace back to you. It's slower than a VPN but provides stronger anonymity.

3. Use a Proxy Server A proxy acts as an intermediary between you and websites. Unlike VPNs, most proxies don't encrypt your traffic, so they're less secure.

4. Check for DNS and WebRTC Leaks Even with a VPN, your browser can leak your real IP through DNS queries or WebRTC connections. Use the FindUtils DNS & WebRTC Leak Test to verify your VPN is working properly.

Common IP Address Myths

Myth 1: Someone Can Find My Exact Address from My IP

IP geolocation resolves to city level at best, typically 80-90% accurate. No one can determine your street address from your IP alone.

Myth 2: My IP Address Is Permanent

Most residential ISPs assign dynamic IP addresses that change periodically, often every few days or when your router restarts. Only static IPs (usually for businesses) remain the same.

Myth 3: Private IPs Can Be Tracked Online

Private IP addresses (10.x.x.x, 192.168.x.x, 172.16-31.x.x) are only valid within your local network. They're not routable on the public internet and cannot be used to identify you online.

Myth 4: Incognito Mode Hides My IP

Incognito/private browsing only prevents your browser from saving history and cookies locally. Websites still see your real IP address. Only a VPN or proxy can hide your IP.

Myth 5: VPNs Make You Completely Anonymous

While VPNs hide your IP, they don't prevent all forms of tracking. Browser fingerprinting, cookies, and logged-in accounts can still identify you. A VPN is one layer of privacy, not a complete solution.

FAQ

Q1: What is my IP address? A: Your IP address is a unique number assigned to your device by your ISP. Visit the FindUtils IP Address Lookup to see your current public IPv4 and IPv6 addresses instantly, along with your location, ISP, and 20+ other details.

Q2: Is the IP address lookup free? A: Yes. FindUtils IP Address Lookup is completely free with no signup, no API keys, and no daily limits for looking up your own IP. The API also offers 120 free requests per minute.

Q3: Can someone find my location from my IP? A: Only approximately. IP geolocation is accurate to the city level (80-90%) but cannot reveal your street address or exact building. Using a VPN changes the location to the VPN server's position.

Q4: What's the difference between IPv4 and IPv6? A: IPv4 uses 32-bit addresses (4.3 billion total) while IPv6 uses 128-bit addresses (practically unlimited). Most modern connections support both. FindUtils shows both your IPv4 and IPv6 addresses automatically.

Q5: How do I hide my IP address? A: The most effective way is using a VPN, which routes your traffic through an encrypted tunnel and shows the VPN server's IP instead of yours. You can also use Tor for stronger anonymity. After connecting to a VPN, use our DNS Leak Test to verify it's working.

Q6: Does my IP address change? A: Most residential ISPs assign dynamic IPs that change periodically. Your IP typically changes when your router restarts or your ISP rotates addresses. Businesses often use static IPs that never change.

Q7: Is it safe to share my IP address? A: Your IP address is not a secret, it's shared with every website you visit. However, you should avoid posting it publicly as it reveals your approximate location and ISP. For privacy, use a VPN when sharing in public forums.

Q8: What is a public vs private IP address? A: Your public IP is assigned by your ISP and is visible to websites. Your private IP (like 192.168.1.x) is used within your local network and is not visible on the internet. The FindUtils tool shows your public IP.
