DNS Lookup
See the live DNS records for any domain. Choose a record type and look it up.
Records appear here, each with its value and how long it may be cached.
What each record type is for
| Type | What it holds | When you would check it |
|---|---|---|
A | The IPv4 address for a name | A site will not load, or you moved it to a new server |
AAAA | The IPv6 address for a name | You want to know whether a site is reachable over IPv6 |
MX | The mail servers for a domain, with a priority each | Email to the domain is bouncing or going to the wrong place |
TXT | Text, mostly for email security and ownership checks | A service asked you to verify a domain, or mail lands in spam |
NS | The name servers that hold the domain's records | You changed DNS provider and want to confirm it took effect |
CNAME | An alias from one name to another | A subdomain should point at a hosted service |
Reading the results
Value is the content of the record. For MX records the priority is shown separately, and the lowest number is tried first.
TTL, time to live, is how long a resolver may reuse the answer before asking again. It is why a DNS change can seem slow: old answers stay in caches until they expire. The value you see here counts down, because the resolver is reporting how much time its cached copy has left.
If you look up an A record and get a CNAME first, the name is an alias. The rows show each step until an address is reached.
"No records found" and "does not exist"
These are different results. No records found means the name exists but has nothing of the type you asked for, which is normal: plenty of domains have no AAAA or MX record. That name does not exist means the name itself is not in DNS, so check the spelling.
How this tool works
Your browser sends the question directly to Cloudflare's public resolver over an encrypted connection. It does not pass through this site's server, and nothing is stored here.
