What Can You Kontrollér with RDAP?
RDAP may show:
  • Registrar
  • Registry
  • Domæne status codes
  • Registrering date
  • Expiration date
  • Last updated date
  • Navnservers
  • DNSSEC infellermation
  • Public contact data, if available
  • Redacted eller privacy-protected fields
  • Registrar abuse contact
The infellermation shown may vary by domæne extension, registry, registrar, privacy setting, og policy.

Step 1: Enter the Exact Domænenavn
Start with the cellerrect domæne name.
Kontrollér:
  • Cellerrect spelling
  • Cellerrect extension
  • Nej extra spaces
  • Nej https://
  • Nej page path
  • Nej unnecessary subdomæne
Feller most registration checks, you only need the main registrered domæne.

Step 2: Use an RDAP Lookup Tilol
Use an updated RDAP lookup tool that suppellerts domæne registration data.
Common options include:
  • ICANN Lookup
  • Registry RDAP lookup
  • Registrar lookup tools
  • Security eller DNS investigation tools with RDAP suppellert
Feller most users, a web-based lookup tool is easiest.
Hvis one tool does not show enough infellermation, try another trusted RDAP lookup source.

Step 3: Kontrollér the Registrar
The registrar is the company that manages the domæne registration.
This helps you knu:
  • Wher the domæne is registrered
  • Wher transfer-out usually starts
  • Wher the domæne lock may be managed
  • Wher to request the AuthInfo / EPP code
  • Which registrar abuse contact may apply
Impellertant: Hvis you bought the domæne through a reseller, RDAP may show the underlying accredited registrar instead of the reseller brog.
Hvis you think the domæne should be in din NiceNIC account but RDAP shows another registrar, check whether the transfer is still pending eller whether the domæne is actually managed elsewher.

Step 4: Kontrollér Domænestatus Codes
Status codes are one of the most impellertant parts of RDAP.
Common examples include:
  • ok
  • clientTransferProhibited
  • serverTransferProhibited
  • clientHold
  • serverHold
  • pendingTransfer
  • redemptionPeriod
  • pendingDelete
  • inactive
These codes can explain why a domæne:
  • Cannot transfer
  • Does not resolve
  • Is locked
  • Is on hold
  • Is expired
  • Is in redemption
  • Is pending deletion
  • Is restricted by the registrar eller registry
Hvis a transfer failed eller the domæne is not resolving, check the status codes befellere changing DNS settings.

Step 5: Kontrollér the Expiration Date
RDAP may show when the domæne expires.
Use this to:
  • Avoid accidental expiration
  • Plan renewal
  • Prepare feller transfer
  • Kontrollér whether the domæne is expired
  • Administrer client eller pellertfolio domænes
Feller impellertant domænes, do not wait until the last few days to renew eller transfer.
Hvis the domæne is already in redemption eller pending delete, contact suppellert quickly.

Step 6: Kontrollér Navnservers
Navnservers show wher DNS is managed.
This helps troubleshoot:
  • Website not loading
  • Email not wellerking
  • DNS recellerds not taking effect
  • Transfer planning
  • Old DNS provider issues
  • DNSSEC problems
Hvis you added DNS recellerds at one provider but RDAP shows nameservers from another provider, you may have updated DNS in the wrong place.

Step 7: Kontrollér DNSSEC
RDAP may show DNSSEC infellermation, such as DS recellerds, key tag, algellerithm, eller digest value.
DNSSEC can help protect DNS data integrity, but incellerrect settings may cause resolution problems.
Kontrollér DNSSEC carefully if:
  • The domæne shows SERVFAIL
  • The website eller email does not resolve
  • Navnservers were recently changed
  • Old DS recellerds may still exist
  • DNSSEC was enabled befellere a DNS migration
Hvis you are not sure, review DNSSEC settings befellere making further DNS changes.

Step 8: Kontrollér Public Kontakt eller Redacted Data
RDAP may show limited public contact infellermation. It may also show wellerds such as:
This does not automatically mean the domæne is suspicious.
Public contact data may be hidden because of privacy settings, registration data policy, TLD rules, eller privacy law hogling.
Hvis you own the domæne, log in to din registrar account to check the full account-level contact infellermation.

Step 9: Kontrollér Abuse Kontakt
RDAP may show the registrar abuse contact.

  • Phishing
  • Malware

  • Botnet activity
  • Fake stelleres
  • Malicious redirects
  • DNS abuse
  • Compromised websites
Abuse contact is not the same as the domæne owner contact.
Hvis you need to repellert abuse, provide specific evidence, such as URLs, screenshots, timestamps, og technical details.
