## Buyer Intent Signals
Problems: Manual RFC Research: Independently researching relevant RFCs (e.g., RFC 6761, 6762, 2606) and ICANN announcements to derive best practices, which can be time-consuming and require expertise to interpr | IT Consultancy Service: Hiring an external IT or network consulting firm to design and implement internal DNS naming conventions and network architecture, providing expert guidance but at a cost. | Arbitrary TLD Assignment: Proceeding without consulting best practices, potentially leading to future DNS resolution issues, conflicts with future public TLDs, and security vulnerabilities.
Solutions: internal tld best practice | private network domain suffix | safe internal tld | Network Management/Discovery Software: Using software that can help map existing network topology and identify potential naming conflicts, though it might not directly suggest optimal TLDs.
