| domain / zonec | string | Optional zone contact, which is for example required for the .de TLD. If the contact is not submitted, the technical contact is used instead. The _[DomainInfo](/en/api/epp-domain-extensions/)_ command returns the zone contact and if was not set, it will be identical to the technical contact. |

A UDRP procedure is running. 3 = lawsuit. Court-ordered decision. 4 = identity. Identity of transfer contact disputed. 5 = nonpayment. Registrant did not pay the domain registration fees. 6 = protest. Objection to transfer by domain registrant or domain admin contact. |
