Complete VPN Testing Guide

Learn how to verify your VPN is working correctly, detect IP leaks, and troubleshoot common VPN connection issues

🚀 Quick VPN Test (30 seconds)

1

Check your IP address before connecting to VPN

2

Connect to your VPN service

3

Check your IP address after connecting

✅ VPN Working: Location changed to VPN server
❌ VPN Failed: Location still shows your real location

Step-by-Step VPN Testing Process

1

Establish Your Baseline

Before connecting to any VPN, you need to know your real network information:

  • Open our IP checker extension
  • Record your Public IP Address
  • Note your Location (city, country)
  • Check your ISP information
  • Screenshot or write down these details
Example Baseline:
IP: 73.158.64.146
Location: Los Angeles, CA, US
ISP: Spectrum Communications
2

Connect to Your VPN

Follow your VPN provider's connection process:

  • Open your VPN application
  • Choose your desired server location
  • Click connect and wait for confirmation
  • Look for "Connected" or "Protected" status
  • Allow 10-15 seconds for connection to stabilize
💡 Pro Tip: Choose a server in a different country than your real location for the most obvious test results.

Verify Your VPN Connection

Now check your network information again:

  • Click the refresh button in our extension
  • Compare the new results to your baseline
  • Verify all information has changed appropriately
  • Take note of any inconsistencies
VPN Working - Example:
IP: 185.159.158.67
Location: London, England, GB
ISP: NordVPN (or your VPN provider)

What Results Mean Your VPN is Working

✅ IP Address Changed

Your public IP should be completely different from your baseline. If it's similar or the same, your VPN isn't working.

✅ Location Changed

The city and country should match your chosen VPN server location, not your real physical location.

✅ ISP Shows VPN Provider

Instead of your real ISP (Comcast, Verizon, etc.), you should see your VPN provider's name or hosting company.

✅ Private IPs Unchanged

Your local private IP addresses (192.168.x.x) should remain the same - only public information changes.

🚨 Warning Signs Your VPN Isn't Working

❌ Same Location Showing

Problem: Your real city/country still appears

Cause: VPN not connected, connection failed, or IP leak

Solution: Disconnect and reconnect VPN, try different server

❌ Real ISP Still Visible

Problem: Your actual internet provider name appears

Cause: Traffic not routing through VPN tunnel

Solution: Check VPN connection, restart VPN app

❌ Similar IP Address

Problem: New IP is very similar to original (e.g., 73.158.64.146 → 73.158.64.200)

Cause: Partial connection or local proxy instead of VPN

Solution: Verify VPN server selection, check for conflicts

❌ Inconsistent Results

Problem: Location shows VPN but ISP shows real provider

Cause: DNS leak or partial VPN connection

Solution: Check DNS settings, use VPN's DNS servers

Advanced VPN Testing Techniques

🔄 Multi-Server Testing

Test multiple VPN server locations to ensure consistent performance:

  • Connect to servers in 3-5 different countries
  • Verify each shows the correct location
  • Note connection speed and stability
  • Check for any servers that leak your real IP

🌐 Multiple Browser Testing

Test your VPN across different browsers and environments:

  • Chrome, Firefox, Safari, Edge
  • Private/Incognito mode testing
  • Mobile browser testing
  • Different devices (phone, tablet, laptop)

⏱️ Reconnection Testing

Test VPN behavior during connection interruptions:

  • Manually disconnect and reconnect VPN
  • Test connection after system sleep/wake
  • Check behavior during network switching
  • Verify kill switch functionality

🚀 Performance Impact Testing

Measure how VPN affects your connection:

  • Compare IP detection speed with/without VPN
  • Test during peak and off-peak hours
  • Monitor for location accuracy changes
  • Check for intermittent disconnections

Troubleshooting Common VPN Issues

VPN Connected But Still Shows Real Location

Possible Causes & Solutions:

  • DNS Leak: Change DNS settings to VPN provider's DNS
  • WebRTC Leak: Disable WebRTC in browser settings
  • Split Tunneling: Disable split tunneling features
  • Cache Issues: Clear browser cache and cookies
  • Time Delay: Wait 30-60 seconds after connecting

VPN Shows Wrong Server Location

Solutions:

  • Disconnect and select a different server
  • Try servers marked as "recommended" or "fastest"
  • Avoid servers that are overloaded
  • Contact VPN support about inaccurate server locations
  • Check if VPN is auto-selecting servers

Inconsistent VPN Performance

Optimization Steps:

  • Update VPN app to latest version
  • Try different VPN protocols (OpenVPN, WireGuard, etc.)
  • Restart your router and modem
  • Disable other VPN or proxy software
  • Check for ISP throttling or blocking

Can't Access Certain Websites with VPN

Workarounds:

  • Try servers in different countries
  • Use "stealth" or "obfuscated" servers if available
