RFC 10023: The "_for-sale" Underscored and Globally Scoped DNS Node Name
In plain English — editorial summary, not part of the RFC
This document defines an operational convention that uses the reserved underscored DNS leaf node name "_for-sale" to indicate the parent domain name is available for purchase. The convention can be deployed without disrupting existing operations, and it may be applied even when the domain name is still actively in use.
