Free DNS lookup & checker
Resolve any domain's A, AAAA, MX, NS, TXT and CNAME records instantly, with quick health checks — handy when a site or its email stops working.
When you'll reach for this
A site that suddenly won't load, email that stopped arriving, a migration that half-worked — the answer is usually in DNS. Checking the live records tells you whether the A record points where it should, whether there are enough nameservers, and whether the mail servers are set up. For client work, monitoring DNS means an unexpected change (or hijack) becomes an alert instead of a mystery outage.
Frequently asked questions
What records does this show?
A and AAAA (the site's IPs), MX (mail servers), NS (nameservers), TXT (SPF/verification), and CNAME (aliases) — plus a few sanity checks like missing A records or too few nameservers.
Why does DNS matter for a client site?
A wrong or changed DNS record can take a site or its email offline, and DNS changes are a common sign of a migration gone wrong or a hijack. Watching it catches those early.
Is this a propagation checker?
It resolves records from our resolver right now. Full propagation-across-the-world checking is a separate concern; for that, re-check over a few hours.
Uptime, SSL, DNS, security and more — with alerts and white-label client reports.
