DNS Lookup — Find DNS Records for a Domain
Look up a domain's DNS records — A, AAAA, MX, TXT, NS, CNAME and more. See exactly how a domain is configured and where its mail and traffic go.
DNS records are the settings that make a domain work: which server serves the site, where email is delivered, which name servers are authoritative, and what verification strings live in TXT records. This tool queries those records and lays them out so you can read a domain's full configuration without dropping to dig or nslookup.
DNS record types at a glance
| Record | What it does |
|---|---|
| A | Maps the domain to an IPv4 address (the server serving it). |
| AAAA | Maps the domain to an IPv6 address. |
| MX | Names the mail servers that receive email for the domain. |
| TXT | Holds free-form text — SPF, DKIM, DMARC, ownership verification. |
| NS | Lists the authoritative name servers for the domain. |
| CNAME | Aliases one hostname to another (e.g. www → root domain). |
A single domain usually publishes several of these at once. Missing or wrong MX/TXT records are the most common cause of email delivery problems.
How to use it
- Enter the domain to inspect.
- Run the lookup to fetch its published records.
- Review each record type and copy the values you need.
Frequently asked questions
- Why don't my recent DNS changes show up?
- Each record carries a TTL that controls how long resolvers cache it. Until that window expires you may still see old values. Lower TTLs propagate faster; higher ones can take a day or more.
- Do I need to include www or a subdomain?
- Enter the exact name whose records you want. The root domain and a subdomain like mail.example.com can have entirely different records, so specify the hostname you're actually troubleshooting.
- My MX records look right but mail still bounces — why?
- MX only points to the receiving server; delivery also depends on that server accepting the mail and on your SPF, DKIM, and DMARC (all TXT records) passing. Check those TXT records too when mail misbehaves.
