# Say in DNS if a domain is for sale

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

- Level: Optional
- Chapter: [HTML basics](https://agentwranglers.se/playbook/website/html-basics)
- Rule: Only if a domain is for sale, say so with a TXT record at `_for-sale`, as RFC 10023 describes. Otherwise publish nothing.
- How: Start the record with `v=FORSALE1;`. Add one content tag, such as `furi=` with a contact address or `ftxt=` with short text. Keep each record under 255 bytes. Remove the record once the domain is sold or off the market.
- Check: `dig +short TXT _for-sale.example.com` returns a record starting `v=FORSALE1;` while the domain is for sale, and nothing otherwise.

Example:

```text
_for-sale.example.com.  3600  IN  TXT  "v=FORSALE1;furi=https://example.com/domain-sale"
```

```sh
dig +short TXT _for-sale.example.com
```
