New RFC 10023 Standard Introduces DNS for-sale Leaf Nodes
A newly introduced informational standard, RFC 10023, establishes the reserved DNS leaf node name _for-sale, allowing active web domains to signal availability for purchase without disrupting live websites, mail servers, or visitor traffic. Registered with IANA, the protocol utilizes TXT records containing version tags and optional parameters like pricing and contact URIs to streamline domain acquisition for brokers and automated services.
Key points
- RFC 10023 was defined as an informational standard in July 2026 to create a reserved DNS leaf node name for domain sales.
- Website operators can publish a TXT record at _for-sale to signal domain availability while keeping their live homepage and email active.
- The record supports mandatory version tags alongside optional fields including asking prices, free text, contact URIs, and proprietary codes.
- The convention is explicitly designed to differ from traditional domain parking by preserving active traffic and separating registration data from purchase intent.
A newly defined internet standard aims to transform how domain availability is communicated across the web. Designated as RFC 10023 and registered with IANA, the protocol introduces a reserved DNS leaf node name known as _for-sale. This mechanism allows website operators to signal that a currently registered and operational domain is open to purchase, without resorting to traditional parking methods that typically replace live content with static sales pages.
The system operates via a TXT record published at the _for-sale subdomain, which carries a mandatory version tag alongside optional value pairs. These parameters can include human-readable text detailing eligibility criteria, contact URIs such as mailto links, specific asking prices with currency amounts like EUR2500.00, or proprietary codes agreed upon by parties.
Industry observers note that this approach directly addresses the gap between basic registration data provided by WHOIS or RDAP and actual market availability. Because the _for-sale record sits passively alongside active site infrastructure, it allows browsers to continue loading regular content and mail servers to function uninterrupted. The intended audience for this standardized signaling method includes automated availability services and professional domain brokers seeking efficient discovery tools.
