That doesn’t look like a domain name. Try something like example.com.au.

Enter a domain (or paste a web address) to see its DNS records.

🔒 Your browser asks a public DNS service directly — lookups never pass through our servers.

domain — string, required. Domain name. A URL or email address also works; the host part is used. Also accepted as d, name.
type — string, default all. Record type(s), comma-separated: A, AAAA, CNAME, MX, TXT, NS, SOA, CAA, or all.

The API answers from our server, and our code doesn’t store what you send. Fair-use limits apply. API guide · all endpoints (JSON) · OpenAPI

What DNS records tell you

DNS is the internet’s address book. When someone types your domain or sends you an email, DNS records say where that traffic should go. Each record type answers a different question:

A and AAAA — the IPv4 and IPv6 addresses of the server your website lives on.
CNAME — an alias: “this name is really that other name”. Common for www and for services like online stores.
MX — the mail servers that receive email for the domain. Lower priority numbers are tried first.
TXT — free-form text. In practice it holds SPF (who may send email as you) and the verification codes that Google, Microsoft and others ask you to add.
NS — the nameservers that hold the domain’s DNS zone. Whoever runs these controls every other record.
SOA — housekeeping details for the zone: the primary nameserver, a contact and a serial number that changes with each edit.
CAA — which certificate authorities are allowed to issue SSL certificates for the domain.

A lookup is the quickest way to answer practical questions: has the change I made actually gone live, who hosts this site, why isn’t email arriving, and are the records still pointing at the old provider after a move? It works for any domain, including .com.au and .au names, and for subdomains such as shop.example.com.au.

I changed a record but still see the old value. Why?

DNS answers are cached. Every record has a TTL (time to live) and resolvers keep the old answer until it runs out, so a change can take from a few minutes to a day or two to be seen everywhere. The TTL shown here is the time left in the resolver’s cache, not the full value set on the record.

Why is a record type missing?

Not every domain has every type. No AAAA record simply means the site isn’t published over IPv6, and many domains have no CAA record. No MX record is the one to watch: it means the domain can’t receive email.

Is the domain I look up sent to Digital Greenhouse?

No. Your browser sends the query straight to Cloudflare’s public DNS service over an encrypted connection, with Google Public DNS as a backup if Cloudflare can’t be reached. Our servers never see which domain you checked.

What does “DNSSEC validated” mean?

DNSSEC signs a domain’s records so they can’t be forged on the way to you. “Validated” means the domain is signed and the resolver checked the signatures. “Not signed” is common and isn’t a fault, but signing is worth considering for domains that handle logins or payments.

Can you manage DNS for my business?

Yes. We look after domains, DNS and email records as part of web hosting and domain names, including moving a site or mailbox between providers without downtime.
