Check a name

One command, straight against the registry — no account, no page to load.

Fills the command and the registrar links below in with your own name. The page is static — nothing is looked up here, and nothing you type leaves the browser.

ds mybrand --tld au

Add --where for the registrars and the registry's rules, --registry for the server that answered, or --all-info for everything at once.

What it costs

Every published quote in the bundled table, cheapest registration first. The figure ds prints beside .au is the mean of the registration column — $29.18, which undercuts 63% of the 881 priced TLDs.

List prices in US dollars, bundled with the binary and last regenerated 2026-09-09. Promotions, ICANN fees, taxes and premium names all move the real number, and a registry may decline to sell you the name at all. See Prices.

Where to register

2 registrars in the bundled table publish a registration price for .au, which is evidence they sell it — nobody prices what they cannot sell. Cheapest first, exactly as ds mybrand --tld au --where prints them.

Put a name in the box above and each link becomes that registrar's search for mybrand.au, where it publishes one. This list is what the price table knows, not the whole market — see Where to register.

Who can register

Australian presence: an Australian business or company number, trade mark, or residency is required.

The same rule governs 6 other zones: .asn.au, .com.au, .edu.au, .id.au, .net.au, .org.au.

Availability and eligibility are different questions, and ds answers the first: a name here reported AVAILABLE means the label is free, not that this registry will sell it to you. The note is hand-maintained and was last checked on 2026-09-02; the registry page it links to, not this one, is the authority. All 81 restricted TLDs, under 27 rules, are listed on Who can register.

How ds answers for it

RDAP first, WHOIS second — the same order for every TLD. .au has both, so RDAP answers and WHOIS is the fallback if it does not.

RDAP
https://rdap.cctld.au/rdapFrom IANA's bootstrap, refreshed when this page was built. The lookup is https://rdap.cctld.au/rdap/domain/mybrand.au — a 404 means the name is free.
WHOIS
domaincheck.auda.org.auQueried on port 43, from the bundled whois.json. The name is called free when the reply contains ---Available — text matching, which is why RDAP is preferred where it exists.

ds mybrand --tld au --registry prints whichever of these answered. If a bundled WHOIS host has gone stale, IANA is asked who serves .au today. See Accuracy notes.

The registry

From IANA's delegation record for .au. .au is a country-code TLD.

Run by
.au Domain Administration (auDA)Based in Australia. Delegated 1986-03-05, record last updated 2026-08-04.
Registry site
www.auda.org.auWhere the registry documents .au — its rules, its accredited registrars, and any launch phases. Not a shop: registries sell wholesale to registrars, not to you.
Published services
rdap.cctld.au · whois.auda.org.auWhat the registry itself tells IANA it runs. Note: the bundled table asks domaincheck.auda.org.au instead — one of them is out of date, and ds falls back to asking IANA when a bundled host goes stale.
Name servers
a.auq.aur.aus.aut.auThe 5 authoritative servers for the .au zone — what the root delegates to. Nothing ds queries directly; they are what makes a registered name resolve.

What it is

Derived from the root zone and ICANN's registry list — each one is a fact with a source.

  • country-code IANA Root Zone Database types it "country-code"

In the root zone

The delegation itself, read out of the root zone — serial 2026090900, on 2026-09-09. The registry section above is IANA's record of what .au was delegated to; this is what the root actually answers with when a resolver asks it where .au lives.

Delegated to
  • a.au58.65.254.12407:6e00:254::1
  • q.au65.22.196.12a01:8840:be::1
  • r.au65.22.197.12a01:8840:bf::1
  • s.au65.22.198.12a01:8840:c0::1
  • t.au65.22.199.12a01:8840:c1::1
The 5 name servers the root hands out for .au, with the glue addresses that come with them — every one of them answers over IPv6. None of this is what ds queries: these servers know which names exist, not who registered them.
DNSSEC
Signed — 1 DS record in the root
  • key 26642RSA/SHA-256 · SHA-2563240A5DA092C3E1BA935CEDFB5289575911B561768C45B3C0EF58A830379146E
Each one is a fingerprint of .au's own signing key, published by the root and signed with the root's key — which is how a resolver that trusts only one key can prove an answer under .au came from its registry and was not tampered with in transit. It says nothing about who owns a name or whether one is free.

Ask the root yourself — no registry involved, and the same records this section was built from: dig +norec @a.root-servers.net au. NS and dig +norec @a.root-servers.net au. DS.
