A DNS lookup shows which records a domain publishes — where its website points, which server handles its email, and what verification records it carries. Here is how to run one and read the results.

What each record tells you

A/AAAA records give the site’s IPv4/IPv6 address. MX records show the mail servers. CNAME reveals aliases. TXT records hold SPF, DKIM, and domain-verification strings. Reading them together explains where a domain’s traffic and email actually go.

Check from outside your network

Running the lookup from an external service (like ours) shows the public, propagated view — which is what matters when a record was just changed or a site is unreachable for others but not for you.

Step by step

1

Enter the domain in the DNS lookup tool.

2

Review the A/AAAA records for the site’s IP addresses.

3

Check MX records to see which servers receive its email.

4

Read TXT records for SPF/DKIM/verification entries when debugging email or ownership.

What records can I look up?›
Common ones include A, AAAA, MX, CNAME and TXT. Our tool returns the domain’s published records.
