Check a name

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

Name

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 xn--55qw42g

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

No registrar in the price table bundled with ds quotes .公益, so the CLI prints no figure beside it — one of 927 such TLDs. That is a gap in the table as often as it is a TLD nobody sells. See Prices for supplying your own table with --pricing-file.

Who can register

No eligibility rule is on file for .公益, which is not the same as a promise that it is open: the list is hand-maintained and covers the restricted TLDs a registrar is likely to offer you. Check the registry's own page before counting on a name. 81 TLDs do carry a rule — see Who can register.

How `ds` answers for it

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

RDAP: https://rdap.ngtld.cnFrom IANA's bootstrap, refreshed when this page was built. The lookup is https://rdap.ngtld.cn/domain/mybrand.xn--55qw42g — a 404 means the name is free.
WHOIS: whois.nic.xn--55qw42gQueried 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 xn--55qw42g --registry prints whichever of these answered. If a bundled WHOIS host has gone stale, IANA is asked who serves .公益 today. See Accuracy notes.

The registry

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

Run by: China Organizational Name Administration CenterBased in China. Delegated 2013-12-12, record last updated 2026-07-21.
Registry site: www.conac.cnWhere the registry documents .公益 — its rules, its accredited registrars, and any launch phases. Not a shop: registries sell wholesale to registrars, not to you.
Published services: rdap.ngtld.cn · whois.nic.xn--55qw42gWhat the registry itself tells IANA it runs. They agree with what ds asks.
Name servers: ta.ngtld.cntb.ngtld.cntc.ngtld.cntd.ngtld.cnte.ngtld.cnThe 5 authoritative servers for the .公益 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"
idn the label is punycode — an internationalised TLD; unicode is how it reads
new-gtld ICANN delegated it on or after 2013-10-23, when the 2013 round opened — see delegated

What it is for

Our reading, not a fact — nothing in the root zone says what a TLD means. Hand-maintained in tld-categories.json.

People & Community Family, friends, charity, and the groups people belong to.

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

Delegated to: ta.ngtld.cn42.83.130.12001:dc7:ffd1::1
tb.ngtld.cn42.83.131.12001:dc7:ffd2::1
tc.ngtld.cn42.83.132.12001:dc7:ffd3::1
td.ngtld.cn42.83.133.1
te.ngtld.cn42.83.134.1
The 5 name servers the root hands out for .公益, with the glue addresses that come with them — 3 of them answer 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 44374RSA/SHA-256 · SHA-2567A835652C46DE71FC431DAD529ADB5722F1DB5239D8A83308B91BCAD79328467
Each one is a fingerprint of .公益'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 .公益 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 xn--55qw42g. NS and dig +norec @a.root-servers.net xn--55qw42g. DS.
