How to use

This tool belongs to the “Network diagnostics” category.

  1. 1Enter a domain, IP or full URL, without stray spaces around the scheme.
  2. 2Run the lookup and wait; multi-region checks need a moment to collect every response.
  3. 3Copy the findings (status code, TTL, latency) and line them up against your own logs.

Your input is processed locally in the browser whenever possible. We do not store it.

Frequently asked questions

Why is the result different from my server?

Checks originate from our own data centre, so the network path differs from yours. Differences are normal for cross-border results or carrier-level caches.

The check timed out

The target may block probes, rate-limit them, or serve only certain regions. Retry with another tool or at another time.

Can it probe private addresses?

No. Loopback, private and reserved ranges are refused so the tools cannot be used to scan internal networks.
