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 mil.br

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 .mil.br, 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

Brazilian presence: a CPF or CNPJ tax registration is required, and a foreign company needs a local representative.

The rule .br sets, which .mil.br inherits as a zone beneath it. registro.br

The same rule governs 41 other zones: .adm.br, .adv.br, .am.br, .arq.br, .art.br, .bio.br, .br, .cng.br, .cnt.br, .com.br, .ecn.br, .eng.br and 29 more.

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

WHOIS
whois.nic.brQueried on port 43, from the bundled whois.json. The name is called free when the reply contains No match for — text matching, which is why RDAP is preferred where it exists.

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

The registry

From IANA's delegation record for .br — .mil.br is a zone under it, so the registry, the servers and the dates below are .br's. .mil.br is a country-code TLD.

Run by
Comite Gestor da Internet no BrasilBased in Brazil. Delegated 1989-04-18, record last updated 2023-11-14.
Registry site
registro.brWhere the registry documents .br — its rules, its accredited registrars, and any launch phases. Not a shop: registries sell wholesale to registrars, not to you.
Published services
rdap.registro.br · whois.registro.brWhat the registry itself tells IANA it runs. Note: the bundled table asks whois.nic.br instead — one of them is out of date, and ds falls back to asking IANA when a bundled host goes stale.
Name servers
a.dns.brb.dns.brc.dns.brd.dns.bre.dns.brf.dns.brThe 6 authoritative servers for the .br 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 .br was delegated to; this is what the root actually answers with when a resolver asks it where .br lives. .mil.br is not in the root zone — nothing below the top level is. It resolves because .br does, on .br's servers.

Delegated to
  • a.dns.br200.219.148.102001:12f8:6::10
  • b.dns.br200.189.41.102001:12f8:8::10
  • c.dns.br200.192.233.102001:12f8:a::10

  • f.dns.br200.219.159.102001:12f8:c::10
The 6 name servers the root hands out for .br, 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

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