🔎 DNS Records Lookup
Fetch A, AAAA, CNAME, MX, TXT, NS, SOA and CAA records for any domain.
What DNS records are
DNS is the internet's address book. When you type a domain into a browser, DNS records decide which server answers, where email is delivered, and which services are allowed to speak for the domain. Every record has a type (what it does), a value (where it points) and a TTL (how long, in seconds, other servers may cache it before checking again). This tool asks a public resolver for the eight record types that cover almost everything a website owner needs to verify.
The record types, in plain English
- A / AAAA, the server's IPv4 / IPv6 address. The record your website cannot work without.
- CNAME, an alias pointing one name at another name (www → the root domain, for example).
- MX, the mail servers that accept email for the domain, with priorities. Covered in depth by our MX Checker.
- TXT, text notes other systems read: domain verification, SPF email rules and more.
- NS, the nameservers in charge of the domain. SOA, the zone's master record, including its serial number.
- CAA, which certificate authorities are allowed to issue SSL certificates for the domain.
Frequently asked questions
I changed a record. Why does this tool still show the old value?
Because of the TTL. Resolvers cache the old answer until it expires, which can take minutes to a day depending on the previous TTL. Our DNS Propagation Checker shows the answer from many resolvers at once, so you can watch the change spread.
What does "No records found" for a type mean?
Simply that the domain does not publish that type, which is normal. Most domains have no CAA or AAAA records, for example. It only matters if a service you use specifically requires that record.
What is NXDOMAIN?
The resolver's way of saying the domain does not exist in DNS at all. Either it is not registered, or it is registered without any nameservers configured.
Which resolver does this tool ask?
Google's public resolver first, with Cloudflare's as a fallback. Both answer from their own caches, so results match what most of the internet currently sees.
