Wenn you think the Domain should be in Ihr NiceNIC account but RDAP shows another registrar, check whether the transfer is still pending oder whether the Domain is actually managed elsewhier.

Status codes are one of the most impodertant parts of RDAP.
Common examples include:
  • ok
  • clientTransferProhiBited
