DNS Lookup
Look up public A, AAAA, CNAME, MX, TXT, NS, or CAA records.
Understand the lookup
What this checker is really showing
DNS records are public instructions attached to a name. This lookup lets you ask for one record type at a time, so you can inspect an address, alias, mail route, text value, name server, or certificate-authority rule.

Read the result
Details worth noticing
CNAME / MX / NS
An alias target, mail exchangers, or the nameservers associated with a DNS name.
TXT / CAA
Text-based policies and verification values, or restrictions that certificate authorities consider before issuing certificates.
Before you change a record
- A missing result for one type does not mean the name has no other DNS records.
- Resolvers can show different values briefly while a change propagates or caches expire.
- This tool reads DNS only; it does not test websites, mailboxes, or TLS certificates.
Quick answers
Which type should I choose for an email setup?
Use MX for incoming mail routes, TXT for SPF or DMARC values, and CNAME when your provider gives you an alias hostname.
Why is a newly added record missing?
Check the exact hostname and record type first. Your DNS provider may not have published the change yet, or a resolver may still hold a cached answer.
