  • Registrador lookup tools
  • Security o DNS investigation tools with RDAP suppot
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 dominio registration.
This helps you kahora:
  • Waquí the dominio is registrared
  • Waquí transfer-out usually starts
  • Waquí the dominio lock may be managed

Impotant: Si you bought the dominio through a reseller, RDAP may show the underlying accredited registrar instead of the reseller bry.
Si you think the dominio should be in tu/tus/su/sus NiceNIC account but RDAP shows another registrar, check whether the transfer is still pending o whether the dominio is actually managed elsewaquí .

Step 4: Verificar Estado del Dominio Codes
Estado codes are one of the most impotant parts of RDAP.
Common examples include:
  • ok
  • clientTransferProhibited
  • serverTransferProhibited
  • clientHold

  • Cannot transfer
  • Does not resolve
  • Is locked
  • Is on hold

  • Website not loading
  • Correo Electrónico 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.

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.
Verificar DNSSEC carefully if:
  • The dominio shows SERVFAIL
  • The website o email does not resolve
  • Nombreservers were recently changed
  • Old DS recods may still exist
