Tools for your website

Where does your domain point?

Check website and email DNS records. Follow the query from root servers all the way to the response from your domain’s servers.

Reading a DNS response

Each record has a purpose

Choose a record type to see which part of your domain it controls.

A / AAAA

Server address

Connect a domain to an IPv4 or IPv6 address. Check them after moving your website.

Email delivery

Identifies mail servers and their priority. Affects incoming messages.

TXT

Verification and policies

Stores text values such as ownership verification, SPF, DKIM and other settings.

NS / SOA

Zone management

Describe authoritative servers and the main DNS zone parameters.

CNAME

Domain alias

Points one hostname to another. Further records determine the destination address.

CAA

Certificate issuance

Specifies which certificate authorities may issue certificates for the domain.

Clear diagnostics

Every record has a job

DNS connects a domain to servers and other services. Select the record type you need: A and AAAA for addresses, MX for email, and TXT for text-based settings. The tool shows the response from its resolver; it does not test worldwide DNS propagation.

01
Enter a domain
Enter a domain or subdomain without a page path, such as example.com or mail.example.com.
02
Choose a mode
DNS records show the resolver’s response. DNS trace reveals the delegation chain and server responses at each step.
03
Read the response
Compare the values with your intended configuration and note the TTL: the time a response may be cached.

Questions and answers

What to know

What can I check with online DIG?

The tool retrieves A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, SRV, PTR, DS and DNSKEY records. Standard mode shows the resolver response; trace mode shows the DNS delegation chain.

What does a DNS trace show?

The trace queries root DNS servers, parent-zone servers and the domain’s authoritative servers in sequence. The result shows delegation, response times and errors for steps actually made. It follows DNS name resolution, rather than tracing the IP network route.

What does TTL mean?

TTL is the time a DNS response may be kept in cache. After a record changes, different resolvers can continue returning an older value for a while. The TTL in a response may show the remaining cache time.

Why is a new DNS record not showing yet?

Check that you changed the active DNS zone on the domain’s current name servers. Then allow for caching. This tool’s result applies to its resolver and does not describe every DNS server.

Does a missing record mean the domain is broken?

Not necessarily. A domain may have no record of the selected type, such as AAAA when it only uses IPv4. Check the record’s purpose, the name itself and the other record types needed by your service.

Are DNS lookups saved?

Yes. Guests can access their history in the same browser for up to 30 days. Signed-in users keep results in their account for up to 365 days, making it easier to compare settings before and after a change.

Check domain DNS records without a command line

Online DIG lets you read a DNS response without installing command-line tools. Check A and AAAA before switching a website, MX when setting up email, and TXT for service values. NS lists name servers, SOA describes the zone and CAA publishes certificate issuance restrictions.

DNS after a website migration

A correct DNS record is only one part of a migration. The new server must accept the domain, the certificate must match the website name and email routes must remain correct. Combining DNS, availability and SSL checks helps verify these steps in order.
