What does a network health check measure?

It combines public IP detection, HTTP-based latency, and download/upload measurements into a quick browser-based overview.

Why does this differ from my ISP's speed test?

Results vary by test server, current network load, and browser conditions; use this as a quick directional check rather than a certified measurement.

Does a high latency result always mean my internet is unhealthy?

Not necessarily. The route to the test endpoint, Wi-Fi conditions, and concurrent network use affect latency. Compare repeated measurements and the needs of your application.

Does this tool identify my exact location?

No. Any IP-based location is approximate and can indicate a city or region rather than a street address.

Network location & ISP

Optional lookup shares the detected public IP with ip-api.com (via the SiteIndex server; its connection uses HTTP, not HTTPS, and results are approximate) and resolves reverse DNS with a DNS-over-HTTPS query to Cloudflare.

Check a domain or IP

Run the same overview against any public target: DNS resolution, HTTP status and response time, TLS certificate expiry, geolocation, and reverse DNS, checked from SiteIndex servers and public DNS.

How to use it

Start the check to gather your public IP, latency, and connection-speed signals.
Review the summary and compare the latency and speed values.
Open the location or ISP details only when you need them for troubleshooting.
Re-run the check under similar conditions to compare a network change.

What is Network Health Overview?

Review your public connection quality in one view with IP detection, latency, and speed checks.

How it works

SiteIndex checks your public IP, HTTP latency, and download/upload throughput in one run. The Advanced panel can additionally look up the approximate location and ISP behind your detected IP.

Common uses

Get a one-click overview of your connection before a call or upload.
Diagnose whether a slow experience is your network or a specific site.
Confirm your ISP and approximate location for a support ticket.

Limitations

Results depend on the browser, network, input, and external service involved.
This tool is informational and does not replace specialist diagnostics or professional advice.
