RDAP + WHOISbrand TLDsold by 1 registrar

Nobody outside the registry can register here. .case is a brand TLD run by Digity, LLC, which under ICANN's Specification 13 means its operator is the only permitted registrant. ds reports names here as PRIVATE rather than AVAILABLE, and leaves the zone out of --tld all unless you pass --private include. See Brand and reserved TLDs.

Check a name

Names under .case cannot be registered, but ds will still tell you what the registry says.

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 case

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 .case is the mean of the registration column — $2599.00, which undercuts 0% 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

One registrar in the bundled table publishes a registration price for .case, which is evidence it sells it — nobody prices what they cannot sell. Cheapest first, exactly as ds mybrand --tld case --where prints them.

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

Who can register

Nobody outside Digity, LLC — see the note at the top of this page.

How ds answers for it

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

RDAP
https://rdap.centralnic.com/caseFrom IANA's bootstrap, refreshed when this page was built. The lookup is https://rdap.centralnic.com/case/domain/mybrand.case — a 404 means the name is free.
WHOIS
whois.nic.caseQueried on port 43, from the bundled whois.json. The name is called free when the reply contains the queried object does not exist — text matching, which is why RDAP is preferred where it exists.

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

The registry

From IANA's delegation record for .case. .case is a generic TLD.

Registry site

Name servers
a.nic.caseb.nic.casec.nic.cased.nic.caseThe 4 authoritative servers for the .case 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.

  • generic IANA Root Zone Database types it "generic"
  • brand ICANN records Specification 13 — a brand TLD, closed to the public
  • new-gtld ICANN delegated it on or after 2013-10-23, when the 2013 round opened — see delegated

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 .case was delegated to; this is what the root actually answers with when a resolver asks it where .case lives.

Delegated to
  • a.nic.case194.169.218.1402001:67c:13cc::1:140
  • b.nic.case185.24.64.1402a04:2b00:13cc::1:140
  • c.nic.case212.18.248.1402a04:2b00:13ee::140
  • d.nic.case212.18.249.1402a04:2b00:13ff::140
The 4 name servers the root hands out for .case, 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 9262ECDSA P-256/SHA-256 · SHA-256FAFB8C8B56BFEC84AB2CB9C6161A8808C53D0535ACEA37DE4C0EAFA2C448A9F6
Each one is a fingerprint of .case'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 .case 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 case. NS and dig +norec @a.root-servers.net case. DS.
