How to use this DNS record checker
- Enter the public DNS name you want to inspect. A website URL includes extra parts; enter example.com rather than https://example.com/page.
- Choose a record type. Use A or AAAA for address records, MX for mail exchangers, TXT for published text, NS for name servers or CNAME for an alias.
- Read the query notice and select Lookup records. Wait for the answer or use Stop lookup to cancel. Changing the name or type clears the previous result.
- Compare the result with the DNS provider's current zone configuration. Query the exact subdomain used by the service, not just the main domain.
Fill example only enters example.com and selects A; it does not send a query until you choose Lookup records. The page runs one query at a time with an eight-second timeout and does not retry automatically.
Which DNS record type should I choose?
| Type | What the data describes |
|---|---|
| A | An IPv4 address associated with the name. |
| AAAA | An IPv6 address associated with the name. |
| MX | A mail exchanger, including its preference value. This is not a mail-delivery test. |
| TXT | Published text, often used for verification or email-policy information. |
| NS | A name-server record for the queried name or delegation. |
| CNAME | An alias pointing to another DNS name. It is not an HTTP redirect. |
An A query can include CNAME records when the resolver follows an alias. The result table preserves each returned record's type rather than treating every answer as an IP address.
Read TTLs and DNSSEC flags carefully
TTL is a cache lifetime expressed in seconds. This page displays the number Cloudflare returned at the time of the lookup; it is not a live countdown. An illustrative TTL of 300 seconds corresponds to five minutes, but it does not mean every resolver worldwide will change its answer within five minutes.
The AD flag is an authentication signal reported by the resolver. AD=true indicates authenticated data in that response. AD=false or an absent flag alone is not a complete diagnosis of DNSSEC configuration. This interface does not independently verify cryptographic signatures or certify a domain's overall security.
No answer, NXDOMAIN and lookup unavailable are different
- NOERROR with no Answer records: the query completed but no answer entries were returned for this query. Check another appropriate type and the precise name.
- NXDOMAIN: Cloudflare reported that the requested name was not found. Check spelling and your authoritative DNS provider. A cached negative answer may persist after a recent change.
- SERVFAIL or REFUSED: the resolver did not provide a successful answer. Validation, upstream conditions or policy may be involved.
- Timeout or HTTPS/browser error: this page could not obtain a usable resolver response. A blocker, network problem, service rate limit or resolver outage is different from a missing domain.
A DNS answer does not establish that a website responds correctly, an email is delivered or your internet connection is fast. Use the slow-internet troubleshooting tool or the Internet Speed Test for their separate tasks.
One named resolver, not a worldwide propagation test
This tool queries Cloudflare 1.1.1.1 only. The result can differ from your ISP's resolver, a VPN, an office split-DNS configuration or a resolver in another location. It does not identify the DNS service currently configured on your device, measure that resolver's speed, test for DNS leaks or query every authoritative server.
The request sends no client-subnet hint. Cloudflare still receives your request IP address; this is not an anonymity service. Read the Cloudflare 1.1.1.1 privacy policy before sending names you consider sensitive. This page provides no query-history feature and does not send names or returned records to its analytics.
DNS lookup questions
What does this DNS lookup check?
It asks Cloudflare 1.1.1.1 for one public DNS name and one selected record type over HTTPS. It displays the returned answer records, TTLs and response code. It does not test website availability or inspect every authoritative server.
Does this show the DNS server my device currently uses?
No. This tool explicitly queries Cloudflare 1.1.1.1. Your browser, operating system, router or VPN may use another resolver. It is not a DNS leak test or a measurement of your configured resolver speed.
Why are there no records for the type I selected?
A NOERROR response with no Answer entries means this query returned no answer records from Cloudflare. Other record types can still exist. An alias may also affect the answer. Check the exact name, selected type and authoritative configuration.
What is the difference between NXDOMAIN and a failed request?
NXDOMAIN is a DNS response saying that the resolver did not find the requested name. A timeout, browser block, rate limit or HTTPS failure means this tool could not obtain a usable answer; it does not establish that the name is missing or the website is offline.
Who receives the name I look up?
After you select Lookup records, your browser sends the DNS name and type directly to Cloudflare 1.1.1.1. Cloudflare also receives connection information such as your IP address and processes it under its DNS privacy policy. This tool does not send the query to a WordPress lookup endpoint or save a lookup history.
Method and useful next steps
Responses come from Cloudflare's documented JSON DNS-over-HTTPS endpoint. The tool checks both the HTTP outcome and DNS response code, validates that the response matches the selected name and type, and displays record data as plain text. It shows at most 100 answer records and identifies a truncated response.
