	tl;dr: RFC 10023 defines a `_for-sale` DNS leaf node where domain owners publish a TXT record (prefixed `v=FORSALE1;`) signaling that an actively-used domain is available for purchase, with optional tags for price (`fval`), contact URI (`furi`), or free text (`ftxt`). Unlike parking, it sits alongside a live site invisibly to browsers, targeting brokers and automated availability checkers rather than humans. Each record holds one tag-value pair, TTL should be ≤3600, DNSSEC signing is recommended, and consumers must treat `ftxt`/`furi` as attacker-controlled input.
	HN Discussion: •Legal concern about publicly declaring a trademarked domain for sale hurting arbitration outcomes ~Proposes alternative Georgist economic model instead of just signaling for-sale status ↓Points out logical flaw that absence of the record cannot imply not-for-sale ↓Opposes the standard because domain squatting itself should be banned rather than facilitated ↓Argues existing well-known email aliases like hostmaster@ already solve the contact problem
