DNS lookup

Free DNS lookup: all records of a domain in one query

Enter a domain and get its records from a public DNS resolver: addresses, mail servers, name servers, text records and the SOA record of the zone.

A request travels from a laptop through layers of DNS servers to the target server

What a DNS lookup shows

DNS turns a domain name into the data other services need: IP addresses for browsers, mail servers for senders, name servers for resolvers and text records for checks like SPF. Each record type answers one of these questions, so the tool asks for them all at once.

The answer comes from a public resolver, the same kind your device uses. Resolvers cache records for the time set in the TTL column. After you change a record, visitors see the new value once the old TTL runs out.

When to check DNS

A site does not open for you, and you want to see where the domain points right now
You moved hosting, mail or DNS provider and want to confirm the new records are live
You prepare a domain for a mail campaign and check MX, SPF and DMARC
You add a proxy host or an API to a whitelist and need its current address

Questions about DNS records

01Why do the results differ from my provider's DNS?

Your provider's resolver may still hold an older answer in cache until its TTL expires. Some domains also return different addresses by region, so resolvers in different places can see different records.

02How long does a DNS change take to reach everyone?

A changed record reaches a resolver once the cached copy expires, which takes up to the old TTL. A change of name servers at the registrar can take up to 48 hours because the registry caches the delegation longer.

03Do you log the domains I check?

No. The page sends the query from your browser straight to Cloudflare DNS or Google DNS. Our server serves only the page and never receives the domain you type.

04Which records does the full lookup show?

Seven types at once: A, AAAA, CNAME, MX, NS, TXT and SOA. The buttons above the field open the PTR lookup for an IP address and each type on its own page.

05What does the TTL in the answer mean?

The number of seconds a resolver caches the record. Lower the TTL to 300 a day before you move a site or mail, and the new addresses spread within five minutes.
