RFC 10023 - A DNS convention for signalling domains for sale
by Marco Davids (Private) 02 Nov '26

02 Nov '26

Hello, I would like to make this group aware of RFC 10023, recently published by the IETF: https://www.rfc-editor.org/rfc/rfc10023 The RFC defines a simple DNS convention for signalling that a registered domain name is currently being offered for sale. It uses a TXT record at a reserved DNS node name: _for-sale.example.com For example: _for-sale.example.com. 300 IN TXT "v=FORSALE1;furi=https://example.com/buy" The idea is to make the sale status of a domain machine-readable and directly discoverable through DNS. The convention requires no changes to DNS protocols or infrastructure. It is entirely voluntary and can be used by domain owners, registrars, registries and service providers. It may also be useful for DNS monitoring, domain intelligence and automated discovery tools. There is already quite some operational experience with this approach. More information, including implementation details and examples, is available at: https://rfc10023.nl/ I thought this might be of interest to people working with DNS and domain infrastructure. Best regards, -- Marco Author of RFC 10023.

According to Kevin Tillery via NANOG <nanog(a)lists.nanog.org>: > Hopefully this helps the registry to discover that the domain is being > boarded, contrary to ToS, and terminate it without refund so we can have less hoarded domains everywhere. Assuming you mean "hoarded", I would be quite interested in pointers to ToS that forbid it, or even define it. R's, John PS: but if it's really boarded, avast mateys, and all that
