What an IP Address Can Reveal—and What It Cannot
An IP address helps networks exchange data. A public IP lookup can return useful network information, but it is not a person's name, a device's GPS location, or proof of who is using a connection.
Public and private IP addresses serve different roles
A public IP address is used on the internet-facing side of a connection. A remote service may see the public address used by your network, which can be a router, workplace gateway, mobile carrier, VPN, or proxy rather than a unique address for your device.
Private IPv4 ranges are reserved for networks that are not directly routed across the public internet. RFC 1918 specifies the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 ranges. A home router commonly assigns private addresses to devices and shares a public connection outward.
IP location is an estimate, not a pinpoint
IP geolocation providers associate address ranges with information such as a country, region, city, or network. The result depends on the provider's data and can vary by network type and address. A lookup can show an approximate area, but it cannot reliably identify a household, street, or individual.
A VPN or proxy may cause a lookup to show the network exit point instead of your own area. Mobile and corporate networks can also route traffic through gateways far from the user.
What happens when you run an IP lookup
An IP lookup needs an address to query. When a page requests results from a geolocation service, that service can see the public IP address used for the request. TheCodePlaza's IP tool uses external lookup providers; review the site's Data Sources and Methodology and Privacy Policy for details about the current tool.
Treat the displayed network and location fields as provider-supplied reference data, not identity proof or a substitute for a service's own account and security records. Different providers can return different results.
Use IP information with care
- Do not assume a city shown by a lookup is the user's exact location.
- Do not use an IP address alone to identify a person or accuse someone of an action.
- If a result looks unexpected, check whether a VPN, proxy, mobile carrier, or organization network is in use.
- Use the IP version and the full address when comparing network details; private IPv4 ranges do not describe every IPv6 address.
Common questions
Can an IP lookup show my home address?
An IP geolocation result is not precise enough to reliably identify a specific household or street. It may return an approximate region, and the result may describe a VPN, proxy, mobile gateway, or other network instead.
Why does my IP location differ from where I am?
Geolocation databases are estimates, and internet traffic may exit through a network gateway in another area. VPNs, proxies, mobile networks, and database differences can all affect the result.
Can a website see my public IP address?
Web services generally receive the public IP address used to connect to them. If you use a VPN or proxy, the service may see that network's address instead of the address assigned by your internet provider.
