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 stc

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 .stc, 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 .stc, 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. .stc has both, so RDAP answers and WHOIS is the fallback if it does not.

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

The registry

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

Run by: Saudi Telecom CompanyBased in Saudi Arabia. Delegated 2015-08-20, record last updated 2024-05-28.
Registry site: www.stc.com.saWhere the registry documents .stc — its rules, its accredited registrars, and any launch phases. Not a shop: registries sell wholesale to registrars, not to you.
Published services: rdap.centralnic.com · whois.nic.stcWhat the registry itself tells IANA it runs. They agree with what ds asks.
Name servers: a.nic.stcb.nic.stcc.nic.stcd.nic.stcThe 4 authoritative servers for the .stc 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"
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 .stc was delegated to; this is what the root actually answers with when a resolver asks it where .stc lives.

Delegated to: a.nic.stc194.169.218.292001:67c:13cc::1:29
b.nic.stc185.24.64.292a04:2b00:13cc::1:29
c.nic.stc212.18.248.292a04:2b00:13ee::29
d.nic.stc212.18.249.292a04:2b00:13ff::29
The 4 name servers the root hands out for .stc, 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 — 2 DS records in the root

Each one is a fingerprint of .stc'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 .stc 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 stc. NS and dig +norec @a.root-servers.net stc. DS.
