Hello,

A while ago, Stephen and I had sent out a few versions of this, and we had some discussions and revisions were made.  At the time, discussion waned, however I wanted to pick this up again before the onset of IETF107.

https://datatracker.ietf.org/doc/draft-brotman-rdbd/

 I've had some folks contact me privately, and I saw an inquiry on another list.  There does seem to be some interest, at least in the anti-abuse and research communities, of making this a functional proposition.

To recap, the rough idea is that implementers would be able to positively or negatively confirm relationships between domains.  In the world of anti-abuse and research, these links are not always obvious.  For example, in a large corporation, some teams may go outside acceptable practice and register a domain through another provider.  Or it may be that you have international branches that operate on a different TLD, but you may not have registered with all TLDs.  In the latter case, being able to both positively and negatively state a relationship could be useful for anti-spam/phishing.

Any questions or comments would be greatly appreciated.  Thank you.
