🌐 IP Address Basics

What is my IP address and why does it matter?

Your IP address is a unique identifier assigned to your device when connecting to the internet. It reveals your approximate geographic location and ISP information. Knowing your IP address helps with network troubleshooting, privacy checks, and verifying VPN connections.

Think of it like your postal address for internet traffic - it tells other computers and websites where to send information back to you.

What's the difference between public and private IP addresses?

Public IP Address: This is how the internet sees your connection. It's assigned by your ISP and visible to websites you visit. Only one public IP per household/business typically.

Private IP Addresses: These are used within your local network (like 192.168.1.100). Each device on your network gets its own private IP. These are not visible to the outside internet.

Our extension shows both types, giving you a complete picture of your network configuration.

Why does my IP address change?

IP addresses change for several reasons:

  • Dynamic Assignment: Most ISPs assign dynamic IPs that change periodically (days to weeks)
  • Network Switching: Moving between home WiFi, mobile data, coffee shop networks
  • Router Restarts: Restarting your modem/router may get a new IP from your ISP
  • VPN Usage: VPNs route your traffic through different server locations
  • ISP Maintenance: Your provider may reassign IPs during network updates

What is IPv4 vs IPv6?

IPv4: The traditional format (like 192.168.1.1) with about 4.3 billion possible addresses. Nearly exhausted globally.

IPv6: The newer format (like 2001:db8::1) with trillions of possible addresses. Being gradually adopted worldwide.

Most networks run "dual-stack" supporting both. Our extension detects whichever your network supports.

🔐 VPN & Privacy Questions

Can I use this extension to check if my VPN is working?

Absolutely! This is one of our most popular use cases:

  1. Before VPN: Check your real IP and location
  2. Connect VPN: Turn on your VPN service
  3. After VPN: Refresh our extension - you should see the VPN server's location

If your location changed to the VPN server location and shows the VPN provider as your ISP, your VPN is working correctly.

What should I do if my VPN is leaking my real IP?

If you still see your real location after connecting to VPN:

  • Disconnect and reconnect to your VPN
  • Try a different server location
  • Check DNS settings - ensure you're using VPN's DNS
  • Disable WebRTC in browser settings if needed
  • Contact VPN support if issues persist

Some VPNs have kill switches that prevent internet access if the VPN disconnects unexpectedly.

Does this extension protect my privacy?

The extension itself doesn't provide privacy protection, but it helps you verify your privacy tools are working correctly. Unlike web-based IP checkers, our extension:

  • Doesn't track your browsing history
  • Doesn't store your IP information
  • Processes everything locally in your browser
  • Doesn't send data to third-party tracking services

Can websites still track me if I know my IP address?

Knowing your IP address is just one part of privacy protection. Websites can still track you through:

  • Cookies and local storage
  • Browser fingerprinting
  • Login information and accounts
  • Device and browser characteristics

Use our extension alongside other privacy tools like VPNs, ad blockers, and privacy-focused browsers for comprehensive protection.

📍 Geolocation & Accuracy

How accurate is the geolocation information?

Accuracy varies by location and provider:

  • Country: 99%+ accuracy worldwide
  • City (Urban): 85-95% accuracy in major cities
  • City (Rural): 70-85% accuracy, may show regional center
  • ISP Information: 95%+ accuracy globally

Mobile networks and satellite internet tend to be less precise than fixed broadband connections.

Why does my location show a different city?

Several factors can cause location inaccuracies:

  • ISP Infrastructure: Your traffic may route through regional hubs
  • Rural Areas: May show the nearest major city or ISP center
  • Mobile Networks: Cell towers can be far from your actual location
  • Corporate Networks: May show company headquarters location
  • Proxy/VPN: Intentionally showing a different location

Can geolocation pinpoint my exact address?

No. IP geolocation typically shows city-level information, not your specific street address. The technology has inherent limitations:

  • ISPs assign IPs to geographic regions, not individual addresses
  • Network infrastructure routing affects apparent location
  • Privacy regulations limit precision of location data
  • Database accuracy varies by provider and region

Your exact location would require GPS data or other precise location services.

What does the ISP information tell me?

ISP (Internet Service Provider) information reveals:

  • Provider Name: Who provides your internet connection
  • Organization: Company or entity that owns the IP range
  • Connection Type: Cable, fiber, DSL, mobile, satellite
  • Network Classification: Residential, business, hosting, mobile

This is highly accurate since ISPs are directly responsible for IP address assignments.

🔧 Network Troubleshooting

How can I use this for network troubleshooting?

Our extension helps diagnose various network issues:

  • IP Conflicts: Check if multiple devices have the same private IP
  • DHCP Issues: Verify devices are getting proper IP assignments
  • Network Segmentation: Understand which subnet you're connected to
  • VPN Problems: Confirm corporate or personal VPN connections
  • ISP Issues: Verify your connection is routing through the correct provider

Why do I see multiple private IP addresses?

Multiple private IPs are normal and occur when you have:

  • Multiple Network Adapters: WiFi + Ethernet + VPN adapters
  • Virtual Machines: VM software creates virtual network interfaces
  • VPN Software: Creates tunnel interfaces with their own IPs
  • Docker/Containers: Container platforms create virtual networks
  • Bluetooth/Mobile: Hotspot sharing or tethering connections

Each represents a different network interface on your device.

What should I do if I can't connect to certain websites?

Use IP information to troubleshoot connectivity issues:

  1. Check your public IP: Ensure it matches your expected location
  2. Verify ISP: Confirm you're connecting through the right provider
  3. Test different networks: Try mobile data vs. WiFi
  4. Check VPN status: Some sites block VPN traffic
  5. Try incognito mode: Rule out browser-specific issues

How do I interpret network subnet information?

Common private IP ranges and their meanings:

  • 192.168.x.x: Most home routers (192.168.1.x or 192.168.0.x)
  • 10.x.x.x: Large networks, corporate environments
  • 172.16-31.x.x: Mid-size networks, some ISPs
  • 169.254.x.x: APIPA/Link-local (indicates DHCP problems)

The specific range tells you about your network's size and configuration.

⚙️ Extension Features & Usage
