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 biz.pr

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 .biz.pr is the mean of the registration column — $103.30, which undercuts 15% 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 .biz.pr, which is evidence it sells it — nobody prices what they cannot sell. Cheapest first, exactly as ds mybrand --tld biz.pr --where prints them.

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

Who can register

No eligibility rule is on file for .biz.pr, 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

Neither an RDAP endpoint nor a WHOIS server is on file for .biz.pr: IANA's bootstrap does not list it and the bundled whois.json has no entry. It is left out of --tld all for that reason, and asking for it by name works only if IANA can name a server for it at the time. Anything ds cannot answer comes back UNKNOWN with the reason attached, never guessed as available.

The registry

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

Run by
Gauss Research Laboratory Inc.Based in Puerto Rico. Delegated 1989-08-27, record last updated 2022-07-20.
Registry site
www.nic.prWhere the registry documents .pr — its rules, its accredited registrars, and any launch phases. Not a shop: registries sell wholesale to registrars, not to you.

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 .pr was delegated to; this is what the root actually answers with when a resolver asks it where .pr lives. .biz.pr is not in the root zone — nothing below the top level is. It resolves because .pr does, on .pr's servers.

The 8 name servers the root hands out for .pr, 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.

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