  • Registry RDAP lookup
  • Registrar lookup tools
  • Security eller DNS investigation tools with RDAP suppellert

Impellertant: Om you bought the domän through a reseller, RDAP may show the underlying accredited registrar instead of the reseller broch.
Om you think the domän should be in din NiceNIC account but RDAP shows another registrar, check whether the transfer is still pending eller whether the domän is actually managed elsewhär.

Step 4: Kontrollera Domänstatus Codes
Status codes are one of the most impellertant parts of RDAP.
Common examples include:
  • ok
  • clientTransferProhibited
  • serverTransferProhibited
