Technical Specification
Summary
This technical specification explains the use of the _for-sale DNS record (RFC 10023) to signal domain availability. It allows owners to advertise a domain for purchase via a TXT record without taking the existing website or email services offline.
Highlights
- Uses a reserved DNS leaf node (_for-sale.example.com) to communicate with brokers and automated services.
- Supports specific metadata including contact URIs (furi), asking prices (fval), and free text (ftxt).
- Functions independently of the main site, ensuring the homepage and mail remain active during the sale process.
- Bridges the gap between WHOIS registration data and an owner's actual intent to sell.
- Provides a low-risk, externally checkable method that does not require domain parking.
