Why run a DNS lookup

A DNS lookup helps you confirm how a hostname resolves before you make routing changes, troubleshoot email delivery, or validate a new domain. It is a fast way to verify A, AAAA, CNAME, MX, TXT, and NS records without installing software.

How the lookup runs

The tool sends a DNS-over-HTTPS request to a public resolver and returns the records it reports. Results update each time you run the lookup, and the test stops when you leave the page.

How to interpret results

Each record shows a type, a value, and a TTL that indicates how long caches may keep it. Compare the returned values to your expected targets, such as your web host or mail provider, and look for missing or unexpected records.

A and AAAA records map a hostname to IPv4 or IPv6 addresses.
CNAME records point a name to another hostname.
MX records define email routing and priority.

This lookup uses a public resolver and may not match your ISP or internal DNS. It cannot query private zones or guarantee global propagation at a specific moment.

Frequently Asked Questions

What is this DNS lookup used for?

This DNS lookup helps you verify how a hostname resolves and whether expected records are published. It is useful for checking web, email, and CDN configurations quickly.

How does the DNS lookup work in the browser?

The tool sends a DNS-over-HTTPS request to a public resolver and displays the returned records. It runs entirely in the browser with no installation.

Which DNS record types can I check with this DNS lookup?

You can check common record types such as A, AAAA, CNAME, MX, TXT, and NS. These cover most web and email configurations.

Is the DNS lookup accurate for my local network?

The DNS lookup uses a public resolver, so it may not match your local or ISP resolver. For internal networks, use your organization’s DNS tools.

Does the DNS lookup show private or internal DNS records?

No, it only queries public DNS records. Private zones and internal hostnames are not accessible from a public resolver.

Why does DNS lookup show different results than my ISP or terminal?

Different resolvers have different caches and may be in different regions. DNS propagation delays can also cause temporary differences between tools.

Is DNS lookup safe and private?

The lookup only sends the hostname and record type to a public resolver. It does not access personal files or store results on this site.

Does DNS lookup work on mobile browsers?

Yes, it works on modern mobile browsers with network access. Results may vary with connectivity and resolver location.

What should I do if DNS lookup returns no records?

First confirm the hostname and record type are correct. If records were just updated, wait for propagation or check the authoritative DNS provider.

Can DNS lookup verify email settings like MX records?

Yes, selecting MX will show the mail hosts and priorities returned by the resolver. Compare them to the settings provided by your email provider.

Why can DNS lookup results change over time?

DNS data is cached and refreshed based on TTL values. Updates, propagation, and resolver caching can all change what you see over time.

What can the DNS lookup not do?

It cannot query internal DNS zones or guarantee worldwide propagation instantly. It only reflects what a public resolver reports at the time of the request.
