VPN IP check

A VPN should change the public IP address seen by websites. A good check compares IP, location, ISP, ASN and browser signals together.

What a VPN changes

When a VPN is connected, your traffic is routed through the VPN provider before reaching websites. The website should see the VPN server's public IP instead of the public IP assigned by your home, office or mobile provider. This can change the country, city, ISP name and ASN shown in an IP lookup.

A VPN does not automatically change every signal. Browser language, timezone, screen size, logged-in accounts, cookies and device behavior can still suggest your real region or identity. That is why a VPN check should not stop at the IP address alone.

VPN check checklist

Public IPShould differ from your normal ISP IP.Check the home page before and after connecting.
Country and cityShould match the VPN location closely.Small city mismatches are common with geolocation.
ISP / ASNOften shows a VPN provider, hosting company or data center.Useful for spotting whether traffic exits through the expected network.
Browser timezoneMay still reveal your device region.Compare on the Browser Information page.
DNS behaviorDNS should usually follow the VPN or trusted resolver.Unexpected DNS can suggest split tunneling or misconfiguration.

How to test your VPN on CheckIP Space

  1. Disconnect the VPN and note your public IP, ISP, ASN and location.
  2. Connect the VPN and refresh the public IP lookup.
  3. Confirm that the public IP changed and the ASN no longer shows your normal ISP.
  4. Open Browser Information and compare timezone, language and platform signals.
  5. If you are checking a domain or server through the VPN, use DNS Lookup, Ping Test and Port Check to compare reachability.

If the IP does not change, the VPN may be disconnected, the browser may be using a proxy override, or split tunneling may be excluding the browser. If the IP changes but location is unexpected, the VPN provider may be using a different data center or an IP range that geolocation databases classify differently.

FAQ

Why does my VPN show a data center ASN?

Many VPN services rent servers or IP ranges from hosting providers. The ASN may show the data center rather than the VPN brand.

Does a VPN hide my browser fingerprint?

No. A VPN changes network routing, but browser properties such as user agent, screen size, language and cookies can remain visible.

Why does my streaming service still know my region?

Services may use account country, payment region, cookies, GPS permissions, DNS behavior, VPN detection lists and browser signals in addition to IP address.

Can a VPN fix a wrong IP location?

It can change the public IP location shown to websites, but the VPN's own geolocation may also be imperfect.

Should I use IPv6 with a VPN?

Only if your VPN supports IPv6 correctly. If IPv6 is not routed through the VPN, websites may see an address outside the VPN path.
