Domain Inspector
What's going on with this website?
Type a website, press Enter. Get its resolved IPs, reachability, and HTTP latency in one shot.
How the domain inspector works
Traditional ICMP ping is blocked by most cloud providers, so it rarely tells you what you want to know about a real website. This tool uses HTTP fetch timing instead — the same path your browser actually takes — and runs DNS-over-HTTPS in parallel to resolve the IP. The result is a single, fast answer: where does this domain point, can I reach it, and how fast? For full DNS record details (MX, TXT, NS, SOA, …) see the dedicated DNS page.

Add a URL below to start monitoring. Polling only happens when you press Start.
Frequently asked questions
What does the domain inspector do?
It runs three checks against a hostname in one shot: it resolves the IP addresses via DNS-over-HTTPS, attempts an HTTP fetch from your browser to measure reachability and round-trip time, and reports the result. The DNS record details live on the dedicated /dns-tools/ page.
Why does the reachability sometimes show "unknown"?
Some websites block cross-origin reads of their responses (CORS). When that happens, the browser still tells us the request completed — so we can usually mark the site reachable — but we cannot read the response body or status code. In that case the result shows "reachable (response not readable)".
What is a good HTTP latency?
Under 100 ms is excellent for most websites. 100-300 ms is typical for cross-continental connections. Over 500 ms will feel sluggish. The number you see is the full request round-trip from your browser, including DNS, TCP, TLS, and the server's response time.
Why is DNS not shown on this page?
The /dns-tools/ page is dedicated to that — it queries every record type (A, AAAA, MX, TXT, NS, CNAME, SOA) at once and renders a grouped view. The domain inspector here only needs the resolved IPs to do the HTTP check, so the rest stays out of the way.
What is the live multi-server ping below?
A power-user feature: add any URL you want to monitor, set a polling interval, and the tool will keep pinging each one from your browser. Polling only happens when you press Start, and only targets you — no central server, no third-party pings. The 9 popular services shown by default are just examples; you can remove them and add your own.
