Understanding the result

Where the data comes from

This lookup uses RDAP, the Registration Data Access Protocol that has replaced traditional WHOIS for generic top-level domains and many country-code domains. Instead of guessing which server to ask, DomainDNSCheck reads the IANA RDAP bootstrap registry, which lists the official RDAP service for every extension that has one, and sends the query there.

RDAP answers in structured JSON, so dates, status codes and nameservers can be shown consistently no matter which registry operates the extension. If you want the background, read What is RDAP? and RDAP vs WHOIS.

What the result shows

  • Registrar: the company the domain is registered through, its IANA ID when published, and the registrar's abuse contact.
  • Status codes: EPP statuses such as clientTransferProhibited, serverHold or pendingDelete.
  • Events: registration, expiration and last-changed dates, shown in UTC.
  • Nameservers: the delegation recorded at the registry.
  • DNSSEC: whether the delegation is signed and any DS data held by the registry.
  • Contacts: for registrant, administrative and technical roles, only the organization and country are displayed.

Below the record you will see findings. Expiry more than 30 days away is a PASS, less than 30 days is a WARNING and a past date is a FAIL. A clientHold or serverHold status, or a deletion status such as redemptionPeriod, is a FAIL because the domain will not resolve or is about to be released. A transfer lock is a PASS; no lock is shown as INFO.

Privacy and redaction

Many registries and registrars redact personal data to comply with privacy laws. When a record contains redaction markers or a privacy notice, the tool shows an INFO finding and leaves those fields empty. It never tries to reconstruct hidden data, and it never displays the personal name, email address or phone number of a registrant, even if the registry publishes them. Business contacts for the registrar and its abuse desk are shown because they exist to be contacted.

When there is no record

A "not found" answer from the registry usually means the name is not registered, but it is worth confirming with the Domain Availability tool, which also looks at DNS delegation. Some extensions, including .np, do not operate an RDAP service at all. For those, the lookup reports that RDAP is unsupported rather than inventing an answer; see Understanding .np domains for how that registry works. If the registry server is slow or unreachable, the result is marked UNKNOWN and you can simply try again later.

Frequently asked questions

Is RDAP the same as WHOIS?

They serve the same purpose, but RDAP is the modern replacement. It returns structured data over HTTPS, supports standardized redaction and has an official directory of servers. Most generic extensions now publish registration data primarily through RDAP.

Why can't I see the owner's name or email address?

Because it is either redacted by the registry or deliberately withheld by this tool. If you need to reach a domain holder, use the contact method offered by the registrar, or the registrar's abuse contact for abuse reports.

The nameservers here differ from what DNS shows. Which is right?

The registry record is the delegation the parent zone should publish, while DNS answers may still come from resolver caches. Differences usually disappear once cached records expire. Compare with the Nameserver Checker and read Understanding nameservers.

Are dates shown in my local time zone?

No. All dates are normalized to UTC, which is how registries record them. Expiry can therefore appear one day earlier or later than a registrar dashboard that uses local time.
