Find DNS Records
This free DNS lookup shows the records a domain publishes: A and AAAA addresses, CNAME aliases, MX mail servers, NS name servers, TXT records such as SPF and site verification, and the SOA record with its serial and refresh timers. Each type sits in its own table with TTLs. Use it after a DNS change, a site move or when email stops arriving.

About this tool
DNS is the address book of the internet, and most "the site is down" or "email is bouncing" problems start there: a record pointing at an old server, a missing MX, an SPF record with a typo, or a CNAME that loops. Hosting panels hide the raw records behind friendly forms, so when something breaks it helps to see exactly what the domain is telling the world.
The lookup asks the DNS resolver on our server for each record type and prints what comes back, grouped by type: A and AAAA addresses, CNAME targets, mail servers with their priority, name servers, every TXT string, and the SOA record with the zone serial and its refresh, retry, expire and minimum values. Choose one type to keep the answer short, or all of them for a full picture. The TTL column shows how long resolvers may cache each record.
Resolvers cache answers, so a change made minutes ago can still show the old value here for up to the old TTL. Records that only exist on subdomains (for example _dmarc.example.com or selector._domainkey.example.com) must be looked up by that full name; the email DNS checker does that for you. Some record types, such as CAA or SRV, are not included.
Frequently asked questions
What is a TTL in DNS?
Time to live: how many seconds a resolver may keep the record before asking again. A TTL of 3600 means up to an hour. Lower it to 300 a day before you change a record so the move is picked up quickly, then raise it again afterwards to reduce lookups.
Why does a lookup for www show a CNAME instead of an address?
A CNAME makes one name an alias of another, so www.example.com often points at example.com or at a hosting platform name. The resolver then follows that alias to find the final address. A CNAME cannot exist at the root of a domain alongside other records, which is why the bare domain uses A records instead.
What do MX priorities mean?
Mail is delivered to the server with the lowest number first; higher numbers are backups used when the first does not answer. Google Workspace and Microsoft 365 publish specific sets of MX records; a domain with no MX record at all usually cannot receive email.
What is in a TXT record?
Free-form text that other systems read: SPF rules listing who may send email for the domain, DMARC policies, domain verification strings for Google, Microsoft or Facebook, and keys for email signing. A domain can have many TXT records, but it should have only one that starts with v=spf1.
My new DNS record does not show up. What should I check?
First confirm the record was saved at the DNS provider that the NS records name, not at an old provider. Then wait for the previous TTL to pass. If the NS records point at a provider you no longer use, the change will never appear until the name servers are updated at the registrar.
