What Is My IP — IP Address Lookup

Check your IP address instantly. Find your public IP, my IP location, ISP, and more with our free IP lookup tool.

How to Use the IP Lookup Tool

Open the page — Your IP address, location, ISP, and ASN load automatically. No typing needed.
Check the map — See where your IP is registered. If it shows a city you don't recognize, your ISP likely routes through a hub elsewhere.
Enter any IP — Type another address into the field to look up someone else's IP or test a VPN server.
Review the details — The ASN tells you which organization owns the IP range. This helps distinguish residential ISPs from cloud providers.

I use this tool most often to verify my VPN is working — check your IP before and after connecting. If the city and ISP change, the VPN is routing traffic correctly.

How Does IP Lookup Work?

When you visit this page, your browser makes a request to a public IP geolocation API (ipinfo.io). The API detects your public IP address and returns data about it — including the city, region, country, ISP, and approximate coordinates. Think of it like a ZIP code, not a GPS coordinate — the location comes from where your ISP registered the IP block, not your device.

Everything happens in your browser. Your IP address is never stored on our servers. The data is shown to you and then discarded when you leave the page.

What Information Does IP Lookup Show?

Public IP address — your device's unique identifier on the internet
Location — approximate city, region, and country based on ISP data
ISP / Organization — the company that provides your internet service
ASN — Autonomous System Number, which identifies the network your IP belongs to
Timezone & Local Time — the timezone associated with your IP's location
Map — approximate location shown on an interactive map

Why Does My IP Address Change?

Most residential connections use dynamic IP addresses. Your ISP picks one from a shared pool, and it can change when your router restarts, your lease expires, or they rebalance their network. It's how they serve more customers with fewer IPs — and it's why you might get a different IP after a power outage or modem reset.

Businesses and servers typically pay extra for static IP addresses that never change. Hosting a website? Running a VPN gateway? You'll want static. A dynamic IP would break your email server the moment it rotated — imagine needing to update DNS records every time your router restarts.

Can Someone Track Me With My IP Address?

Your IP address reveals your approximate city and ISP, but it can't pinpoint your exact street address or reveal your identity. Law enforcement can request subscriber information from your ISP with a warrant, but a random person on the internet can't find your home address from your IP alone. For additional privacy, use a VPN which replaces your real IP with the VPN server's IP.

How Accurate Is IP Geolocation?

IP geolocation accuracy varies by region and ISP. In dense urban areas, it may be accurate to within a few blocks. In rural areas, it can be off by 50 miles or more. The location shown is based on where your ISP registered the IP block, not your physical address. DNS-based geolocation is generally more accurate than IP-based.

When to Use an IP Lookup

Beyond simple curiosity, an IP lookup comes in handy more often than you might expect. I've used mine to figure out why a blog was rejecting my comments (turned out my IP was from a range flagged for spam), to double-check that my VPN was actually working after switching servers, and to explain to a friend why their streaming service showed the wrong language — their ISP was routing through a different city.

Server admins run IP lookups to verify that cloud instances are deployed in the right regions. Security analysts use them during incident response to identify the origin of suspicious traffic. Even regular web users benefit from checking their public IP when setting up remote access to a home server, configuring a firewall rule, or troubleshooting why a specific website won't load.

Frequently Asked Questions

What is my private IP?

Your private IP is used within your home or office network (typically starting with 192.168.x.x, 10.x.x.x, or 172.16.x.x). This page shows your public IP — the one visible to the internet. To find your private IP, check your device's network settings.

Do you store my IP address?

No. Your IP address is fetched in real time from public APIs and displayed only in your browser. We don't log, store, or share your IP address or lookup history.

Is IPv6 supported?

Yes. Our tool detects both IPv4 and IPv6 addresses. If your ISP provides IPv6 connectivity, you will see your IPv6 address alongside IPv4 information.

What is an ASN and why does it matter?

An Autonomous System Number (ASN) identifies the network your IP belongs to — think of it as a license plate for an ISP or cloud provider. When our lookup shows AS13335 (Cloudflare) or AS15169 (Google), it tells you which organization actually owns that IP range. This is useful for distinguishing residential ISPs from datacenter providers during network troubleshooting.

Can I look up someone else's IP address?

Yes — enter any IP address in the field. The tool doesn't restrict lookups to your own IP. You can check any public IP address. Just keep in mind that the location shown is based on ISP registration data, not real-time GPS tracking.
