DNS Lookup — free online tool

Inspect A, AAAA, MX, NS, and TXT records for a hostname via Cloudflare DNS JSON—no terminal required.

Saves opening a terminal or a separate DNS client for one-off checks.

How to use DNS Lookup

Enter a hostname on DNS Lookup (example.com without path).
Choose record type A, AAAA, MX, NS, or TXT as offered.
Run lookup via Cloudflare or Google DNS JSON in the browser.
Copy answers into ticket notes or compare MX priorities for mail debugging.

Practical tips

Check A/AAAA for hosting, MX for email, and TXT for SPF/DKIM when debugging delivery.
Recent DNS changes may be cached—results can lag the authoritative record by minutes to hours.
Compare against a second resolver if a record looks stale or wrong.

Limitations

DNS Lookup sees URLs the same way a third-party proxy would. VPNs, firewalls, and ad blockers can change status codes compared with your server logs.

Privacy & data

Queries go from your browser to public APIs (DNS, HTTP metadata, translation, prayer times, etc.). Webtoolshop does not log them on our static hosting, but those services may record requests like any website you visit. Avoid internal URLs and secrets.

Frequently asked questions about DNS Lookup

Is the DNS Lookup free on Webtoolshop?

Yes. There is no sign-in and no paywall on this page. We may show advertising on some layouts to cover hosting.

Can I use the DNS Lookup on a phone?

Yes for light tasks. Very long pasted text, huge images, or multi-megabyte PDFs are easier on a laptop with more memory.

Why might the DNS Lookup show a different result than my terminal?

Public APIs use their own caches, rate limits, and data sources. VPNs, ad blockers, and corporate DNS can also change what you see compared with a server-side dig or whois command.
