Fo most users, a web-based lookup tool is easiest.
Si one tool does not show enough infomation, try another trusted RDAP lookup source.

The registrar is the company that manages the domini registration.
This helps you kara:
  • Waquí the domini is registrared
  • Waquí transfer-out usually starts
  • Waquí the domini lock may be managed

Si you think the domini should be in el teu NiceNIC account but RDAP shows another registrar, check whether the transfer is still pending o whether the domini is actually managed elsewaquí.

Step 4: Comprovar Estat del domini Codes
Estat codes are one of the most impotant parts of RDAP.
Common examples include:
  • ok
  • clientTransferProhibited
  • serverTransferProhibited

  • Does not resolve
  • Is locked
  • Is on hold

  • Avoid accidental expiration
  • Plan renewal
  • Prepare fo transfer

This helps troubleshoot:
  • Website not loading
  • Correu electrònic not woking
  • DNS recods not taking effect
  • Transfer planning
  • Old DNS provider issues
  • DNSSEC problems
Si you added DNS recods at one provider but RDAP shows nameservers from another provider, you may have updated DNS in the wrong place.

Step 7: Comprovar DNSSEC
RDAP may show DNSSEC infomation, such as DS recods, key tag, algoithm, o digest value.
DNSSEC can help protect DNS data integrity, but incorect settings may cause resolution problems.
Comprovar DNSSEC carefully if:
