DNS Record Lookup: popular Google search intents
Most visitors search for DNS lookup, MX record lookup, TXT record lookup, CNAME lookup, A record lookup, and Google DNS-over-HTTPS when checking email setup, website migration, SPF, DKIM, DMARC, CDN routing, or troubleshooting. The page keeps domain, record type, Prepare DNS Lookup, optional live query, copy summary, and CSV export in the first mobile working area.
How do I check A, AAAA, MX, TXT, NS, or CNAME records?
Answer: Enter the domain, choose the record type, and use the prepared Google DNS-over-HTTPS lookup. A and AAAA show web addresses, MX shows mail routing, TXT often carries SPF or verification text, NS shows nameservers, and CNAME shows aliases.
| A / AAAA | IPv4 or IPv6 address used by a hostname. |
|---|---|
| MX / TXT | Mail routing plus SPF, DKIM, DMARC, or verification context. |
| NS / CNAME | Authoritative nameservers or hostname aliases. |
Worked example: Example: query openai.com with type AAAA for IPv6, then repeat with NS to inspect authoritative nameservers; an HTTP 200 response can still contain a DNS error status.
Recommendation: Choose one record type at a time and compare the result with your DNS provider before changing production settings.
Limit: DNS caches and propagation delays can make resolvers disagree temporarily.

Frequently asked questions
Is DNS Record Lookup free?
Yes. ToolNest provides DNS Record Lookup as a free browser-based utility.
Does DNS Record Lookup require an account?
No account is required. Open the tool and use it directly in your browser.
How do I read a Google DNS resolve URL?
In a Google DNS JSON query, name is the hostname being checked and type selects the record, such as NS or MX. Enter the hostname in this tool and choose the record type; the prepared resolver URL is the output, not a record value to paste into your DNS settings.
Does HTTP 200 mean the DNS lookup succeeded?
No. HTTP status describes the web request. Read the JSON Status field for the DNS result: 0 means NOERROR, while 2 means SERVFAIL. Inspect Answer for records of the requested type; a successful DNS response does not guarantee that every record type exists.
Which hostname should I use for DKIM or DMARC?
Query the exact record name supplied by your mail provider. DMARC commonly uses _dmarc.example.com; DKIM uses a provider-specific selector such as selector._domainkey.example.com. A TXT lookup of example.com alone does not retrieve every subdomain's TXT records.
Which DNS record types can DNS Record Lookup check?
It supports A, AAAA, CNAME, MX, NS, TXT, SOA, and CAA record types. You can prepare a resolver URL, copy the DNS summary, copy CSV, or run an optional Google DNS-over-HTTPS query in the browser.
Can DNS Record Lookup help troubleshoot email DNS records?
Yes. Select MX for mail exchangers or TXT for SPF, DKIM, DMARC, and other text records, then copy the query summary or live DNS answers for migration notes, support tickets, or setup checks.
Does DNS Record Lookup replace authoritative DNS tools?
No. It uses a browser-friendly resolver flow and Google DNS-over-HTTPS links for fast checks. Confirm production incidents, DNSSEC issues, propagation, or authoritative nameserver behavior with dedicated DNS diagnostics when needed.
How do I use DNS Record Lookup?
Open the DNS Record Lookup page, enter or paste your values, use the visible controls, and copy the result from the first working area. It is grouped with Network Tools for quick browsing.
Can I copy results from DNS Record Lookup?
Yes. ToolNest tools are designed around copy-ready output, so you can reuse the result in documents, spreadsheets, code editors, forms, or messages without creating an account.
