Internet diagnostic tool

VPN route and IP check

When a VPN is enabled, your visible IP and route can change. This page helps you compare IP, latency, jitter, and stability before and after connecting to a VPN.

Ready to test

Test if your internet is actually good enough

Run a quick browser-based diagnostic for calls, gaming, streaming, VPN, and remote work. Verdicts appear before raw technical numbers.

MVP note: latency, jitter, packet loss, and speed are browser-based estimates. Fetch failures/timeouts approximate packet loss and may be affected by blockers, CORS, or third-party test endpoints.

VPN route and IP check: what the results mean

When a VPN is enabled, your visible IP and route can change. This page helps you compare IP, latency, jitter, and stability before and after connecting to a VPN.

What to compare

  • Visible public IP.
  • Approximate location and ISP/network name.
  • Latency before and after VPN.
  • Jitter and packet loss before and after VPN.

When to avoid VPN

  • Competitive gaming.
  • Important video calls if jitter rises.
  • Streaming if VPN reduces download speed.
  • Any app where low latency matters more than privacy.

Frequently asked questions

How do I check if my VPN changed my IP?

Open the IP check page with VPN off, then turn VPN on and check again. The visible IP and location should change.

Can VPN routing hurt calls?

Yes. Distant or overloaded VPN routes can raise latency and jitter, hurting Zoom, Teams, and gaming.

Is this a full DNS leak test?

No. This MVP checks visible IP and connection quality; a full DNS/WebRTC leak test can be added later.

WiFi causing packet loss?

If Ethernet is better than WiFi, a stronger router or mesh setup may help.

Speed still too low?

If multiple tests show weak speeds, compare broadband options or upgrade your plan.
