IP addresses and VPNs: what changes?
An IP address helps route internet traffic. When a VPN is connected and carrying a request, a website will generally see the VPN server’s public IP address instead of the public IP address used by your internet connection. The details depend on your device, app, and network configuration.
Public and private IP addresses serve different roles
A public IP address is used to communicate across the internet. A private address is used inside a local network, such as your home Wi-Fi. Your router commonly shares one public connection across devices; sites generally see the public address from which their traffic arrives.
Assigned by an internet provider or network. It can provide clues about a network or approximate region, but it does not reliably identify a person or exact street address.
Used for communication within a local network. Addresses such as 192.168.x.x are not normally the public address a website sees when you visit it.
Your visible address usually becomes the VPN endpoint’s
A VPN creates a connection between your device and a VPN server. For traffic routed through that tunnel, the destination site generally receives the server’s public IP as the connection source. The VPN provider can see the connection from your device and the traffic leaving its server, subject to encryption and the service’s design.
What a VPN can change
- The public source IP address visible to sites for traffic routed through the VPN.
- The network path between your device and the VPN server.
- The apparent network location associated with that VPN endpoint, as estimated by websites and databases.
What it does not automatically change
- Your account identity, cookies, browser fingerprint, or information you choose to share.
- Your device’s private address on a local network.
- Every app’s route: split tunneling or unsupported traffic may bypass the VPN.
Compare the address before and after connecting
- Check your usual connectionUse a reputable IP lookup page and note the public IPv4 and, if shown, IPv6 address. Avoid posting the result publicly.
- Connect the VPNChoose a server and wait for the VPN app to report that the connection is active.
- Check againReload the lookup page. For traffic covered by the VPN, the displayed public address should generally correspond to the VPN exit network.
Repeat the check in the browser or app you actually use. A single webpage check does not prove every app, protocol, or future connection is routed the same way.
Check the route and app settings
- Confirm the VPN says it is connected and reconnect if needed.
- Check whether split tunneling excludes the browser or app you tested.
- Review IPv6 support and leak protection in the VPN documentation.
- Try a second lookup service, since address databases can be inaccurate.
IP address and VPN FAQ
Does a VPN give me a new IP address?
For traffic routed through the VPN, websites generally see the VPN server’s public IP. The address may be shared with other customers or may change when you switch servers; provider configurations vary.
Can someone find my exact address from an IP?
An IP address may suggest a network or approximate location, but geolocation is not exact and an address alone does not reliably identify a person or home address. Other records may be relevant to an investigation.
Why does my location still look wrong?
Websites estimate location using IP databases that can be outdated or inconsistent. Your account, browser settings, device location permission, or other signals may also affect what a website displays.
Should I share my IP address in a screenshot?
Treat it as information about your connection and blur it before sharing publicly. The privacy impact depends on context, but it is usually unnecessary to expose it in a public post.
