Knowing which registrar manages a domain is essential for domain management, transfers, and troubleshooting. When you need to update DNS records, renew a domain, or initiate a transfer, you need to know the registrar. For domains you do not control, registrar information helps you understand who to contact for abuse reports, domain purchases, or partnership inquiries.

The lookup_domain skill identifies the registrar for any domain along with their contact information and the domain current status codes. Status codes like serverTransferProhibited, clientDeleteProhibited, and others tell you about the domain transfer and modification restrictions. This information is critical for domain portfolio management, transfer planning, and security verification.
