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 xn--3e0b707e

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 .한국, 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 .한국, 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. .한국 has no RDAP service, so the answer comes from WHOIS text on port 43.

WHOIS
whois.krQueried on port 43, from the bundled whois.json. The name is called free when the reply contains not found — text matching, which is why RDAP is preferred where it exists.

ds mybrand --tld xn--3e0b707e --registry prints whichever of these answered. If a bundled WHOIS host has gone stale, IANA is asked who serves .한국 today. See Accuracy notes.

The registry

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

Run by
KISA (Korea Internet & Security Agency)Based in Korea (the Republic of). Delegated 2011-02-05, record last updated 2023-03-07.
Registry site
www.nic.or.krWhere the registry documents .한국 — its rules, its accredited registrars, and any launch phases. Not a shop: registries sell wholesale to registrars, not to you.
Published services
whois.krWhat the registry itself tells IANA it runs. They agree with what ds asks.
Name servers
b.dns.krc.dns.krd.dns.kre.dns.krf.dns.krg.dns.krThe 6 authoritative servers for the .한국 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"
  • idn the label is punycode — an internationalised TLD; unicode is how it reads

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

Delegated to
  • b.dns.kr210.101.60.1
  • c.dns.kr210.101.61.1
  • d.dns.kr203.83.159.12001:dcc:4::1
  • e.dns.kr202.30.124.1002001:dcc:5::100
  • f.dns.kr210.101.62.12001:dcc:6::1
  • g.dns.kr202.31.190.12001:dc5:a::1
The 6 name servers the root hands out for .한국, with the glue addresses that come with them — 4 of them answer over IPv6. None of this is what ds queries: these servers know which names exist, not who registered them.

Each one is a fingerprint of .한국'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 .한국 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--3e0b707e. NS and dig +norec @a.root-servers.net xn--3e0b707e. DS.
