_for-sale DNS records

The post describes a lightweight DNS convention for advertising that a domain is for sale. Owners can publish a special record under `_for-sale` and optionally include fields like minimum price, landing page, or contact details. It is not a binding offer. It is just a standardized machine-readable way to say “this domain may be available,” aimed at brokers, registrars, and lookup tools.

If you own domains, this is another signal that resale workflows are getting more formalized and registrar tools will likely surface them more often. If you are naming a product or company, assume desirable domains remain a market with legal and pricing traps, not a simple registration step.

Discussion mood

Mostly negative and dismissive. People saw the idea as helping squatters, inflating an already frustrating domain market, and dressing up a weak convention as a standard. The strongest pockets of interest were around the legal clarifications on UDRP and the few concrete examples of existing implementations.

Key insights

  1. 01

    UDRP does not treat sale listings as automatic bad faith

    Publicly advertising a domain for sale is not enough on its own to lose a Uniform Domain-Name Dispute-Resolution Policy case. The stronger test is whether the name was registered mainly to sell to a specific trademark holder, whether the mark was already distinctive or famous, and whether the registrant has any believable non-trademark reason to own it. That distinction matters because it separates legitimate domain investing in generic terms from brand-targeted registrations, which is where panels usually find bad faith.

    Do not rely on the folk wisdom that a visible sale listing is fatal. If you hold a domain that overlaps with a mark, document why you registered it and whether that reason existed before any buyer appeared.

    Legal cost is the real leverage

    Even a defensible domain can be hard to keep because the economics favor the party with deeper pockets. Several comments made the point bluntly that trademark fights and related litigation often become wars of attrition, especially in the United States where fee recovery is limited and uncertain. The practical result is that rights on paper do not prevent coerced settlements in the real market.

    Treat domain risk as a budget problem, not just a legal analysis problem. If a name is core to your business, plan for trademark clearance and defense costs early or pick something you can actually afford to protect.

    SIDN already ships a partial version

    The Dutch `.nl` registry operator SIDN already exposes whether some domains are for sale in its WHOIS results, but it does so through its own internal system rather than by honoring the full proposed DNS metadata. That is a useful reality check. The hard part is not inventing a record format. It is getting registry and registrar workflows to consume it in a way users actually see.

    Judge this proposal by downstream integrations, not by the record syntax. If registrars and registries do not surface it in search and transfer flows, it will stay niche.

    The domain market is already shaped by premium pricing

    A few comments pointed out that registries and registrars already monetize desirable names aggressively through premium domains, brokerage, and aftermarket support. In many newer top-level domains, short or attractive names can cost thousands per year before any third-party squatter gets involved. That means speculation is not just a side effect of the system. In many cases it is built into the business model of the operators themselves.

    When choosing a name, evaluate the registry economics of the top-level domain itself. A clever non-`.com` can look available and still lock you into premium renewal pricing or a resale-heavy ecosystem.

    Underscore records avoid most subdomain collisions

    The concern that a user-created subdomain named `_for-sale` could create chaos got a solid technical answer. Names beginning with an underscore are effectively reserved for special DNS uses, and platforms that let users create hostnames generally should block them alongside names like `www` and `.well-known`. The edge cases are messier for wildcard-hosted platforms and second-level structures such as `example.co.uk`, but the basic naming choice is not arbitrary. It follows existing DNS convention.

    If you run a platform that provisions customer subdomains, audit your reserved-name filters. Blocking underscore-prefixed labels is part of basic hygiene, not a niche DNS feature.

Against the grain

  1. 01

    Even a weak signal beats silence

    The cleanest defense of the proposal was that a standardized “for sale” marker does not need to solve the whole domain market to be useful. Absence cannot mean “not for sale,” but presence can still save time by giving buyers an explicit machine-readable path instead of forcing WHOIS scraping, parked pages, or dead contact forms.

    If you operate tools that inspect domains, treat this as an optional positive signal rather than a definitive market status. That modest use case is realistic even if the grander claims are not.

    Nonbinding sale intent can still be desirable

    A few comments argued that making the record nonbinding is a feature, not a flaw. Owners may want to signal openness to offers without committing to sell to every bidder, and in some cases they want to favor a mission-aligned buyer over the highest price. That makes the record closer to an invitation to negotiate than a “buy now” button, which fits how many domain holders actually think about valuable names.

    If you list a domain, be explicit elsewhere about whether the number is informational, a floor, or an actionable offer. Buyers will otherwise project stronger expectations onto the record than it really carries.
