How to Check If Your VPN Is Working With an IP Lookup
Use public IP lookup, location checks, and DNS tests to verify whether your VPN is actually changing your visible network identity.
Start with your public IP
Before connecting to a VPN, check your public IP and note the country, city, and ISP. After connecting, run the lookup again.
A working VPN should usually show the VPN provider or exit network instead of your normal home, office, or mobile ISP.
Do not rely on city alone
VPN city labels and IP geolocation databases can disagree. A server marketed as one city may appear in a nearby metro or at a hosting provider location.
Focus on whether your original public IP and ISP are hidden, not whether every database agrees on the exact city.
Run privacy checks together
Public IP lookup checks what websites see. DNS leak tests check resolver behavior. Browser leak tests can check WebRTC and IPv6 exposure.

How to read proxy and VPN signals without overblocking
VPN and proxy detection is a context signal. Many legitimate users rely on privacy tools, workplace VPNs, or travel connections. The important question is whether the action being attempted is sensitive enough to require more proof.
Anonymous infrastructure becomes more concerning when it appears with automation, high fraud scores, repeated signups, payment attempts, credential attacks, or inconsistent device signals. Without those patterns, a proxy result may only deserve logging or a lightweight challenge.
A healthy policy separates browsing from high-risk workflows. Allow ordinary access where possible, then add verification for account recovery, checkout, admin actions, token creation, bulk scraping, or repeated failed authentication.
For a live example, run the relevant address through Crafzo IP Lookup or open the What Is My IP Address to compare the article guidance with real lookup fields.
Signals to compare before acting
| Signal | What to check | Practical use |
|---|---|---|
| VPN or proxy flag | Is the address known or likely to be anonymized? | Use as a reason for extra verification on sensitive actions. |
| Hosting or data center | Does the provider look like cloud, server, CDN, or VPN infrastructure? | Useful for separating consumer sessions from automation-friendly networks. |
| Location mismatch | Does the visible location conflict with account, shipping, billing, or recent login history? | Good review signal when paired with stronger account evidence. |
| Behavior | Are requests too fast, too broad, or repeated across many accounts? | Behavior confirms whether the privacy tool is becoming abuse. |
Practical checklist
- Do not block every VPN user by default.
- Challenge VPN or proxy sessions only when the workflow is sensitive.
- Compare provider, ASN, and behavior before enforcement.
- Document whether the issue is privacy-tool use or actual abuse.
Frequently Asked Questions
Why does my VPN show the wrong city?
Geolocation databases can map VPN IPs to nearby or registered network locations instead of the app label.
Should my ISP name disappear?
Usually yes. If your normal ISP still appears, the VPN may not be protecting that connection.
