IP Address Lookup — Find Your IP & Geolocation Online

What Is a Public IP Address?

Every device connected to the internet has an IP address (Internet Protocol address) — a numerical label that identifies it on the network. Your public IP address is the one your ISP assigns to your router, and it is the address that websites, servers, and services see when you connect to them.

Unlike your private IP (the 192.168.x.x address on your home network), your public IP is the same for every device on your network. Everyone in your household shares the same public IP address.

IPv4 vs IPv6

The internet is running out of IPv4 addresses. ISPs increasingly assign IPv6 addresses, and many devices now have both (dual-stack). The lookup tool supports both IPv4 and IPv6.

What Does IP Geolocation Reveal?

IP geolocation databases map IP address ranges to geographic locations. The lookup tool shows:

• City and region — approximate location of your ISP infrastructure
• Country — generally accurate
• ISP / Org — the organization that owns the IP block
• Timezone and UTC offset — based on the ISP location
• Coordinates — latitude/longitude of the approximate location

Geolocation is not GPS — it reflects the location of your ISP's infrastructure, which may be in a different city than your physical location. Accuracy varies: country-level is nearly always correct; city-level is usually within 50 miles for residential connections.

VPN and Proxy Detection

When you use a VPN, all your traffic routes through the VPN server. The lookup tool will show the VPN server's IP and location, not your actual location. This is the core privacy mechanism of a VPN — from the outside, you appear to be in the VPN server's location.

The ISP field is a useful indicator: residential IPs show your ISP's name; VPN and proxy IPs typically show the hosting provider or data center name (e.g. "Amazon", "DigitalOcean", "Cloudflare").

Common Uses for IP Lookup

Verifying your VPN is working

Open the IP lookup tool before and after connecting to your VPN. If the IP and location change, the VPN is routing your traffic correctly.

Debugging geolocation in web apps

If your web application uses IP-based geolocation for content localization, currency, or regional access control, this tool helps you quickly check what location your development IP would be assigned.

Network troubleshooting

ISP and organization information helps identify if an IP belongs to a cloud provider, residential ISP, or corporate network — useful for diagnosing unexpected traffic sources in server logs.

Private IP Addresses

Some IP ranges are reserved for private networks and cannot be geolocated:

• 10.0.0.0/8 — large private networks
• 172.16.0.0/12 — medium private networks
• 192.168.0.0/16 — home and small office networks
• 127.0.0.1 — localhost (your own device)

Entering these addresses in the lookup tool will return an error, since they are not routed on the public internet and have no geolocation data.
