Which address are you seeing?
The automatic panel shows the public address of the connection reaching this site. It is not a list of addresses on your device.
- Read the address and note whether it is IPv4 or IPv6.
- If comparing connections, note Wi-Fi, mobile data, and VPN state.
- After changing networks, refresh the page; the earlier result describes the earlier connection.
- Public IP
- Visible to the site; it may be shared behind NAT.
- Local IP
- Used inside your Wi-Fi or wired network, for example for a printer.
- VPN exit
- May replace the public address seen by a site when its traffic follows the tunnel.
Location and network data: ipwho.is. Availability and accuracy depend on the provider.
QUICK ANSWERS
A little more clarity.
What you should know about IP addresses.
What can an IP lookup tell me?
See the approximate location, internet provider, network, and time zone of a public IP address. It does not reveal a person’s name, phone number, or home address.
Is the location precise?
IP location is approximate, not GPS data. VPNs, mobile networks, and provider routing can make an address appear in a different city.
How does bulk lookup work?
Paste up to 20 addresses on the bulk lookup page. Separate them with new lines or commas. Duplicate addresses are queried once. Download the results as CSV.
How is lookup data processed?
The queried IP address is sent to ipwho.is to retrieve location information. This application does not maintain a query history database; hosting and data providers may retain technical logs. Your language is determined by the page address.
