Folks, we could really use feedback from people with DNS expertise to help document a set of best practices for managing existing DNS delegations at the TLD level when EPP domain and host objects are deleted. As described in this draft:
https://datatracker.ietf.org/doc/draft-hollenbeck-regext-epp-delete-bcp/ EPP includes recommendations to not blindly delete objects associated with existing delegations because, among other reasons, doing so can lead to DNS resolution failure. That's led some domain name registrars to implement creative practices that expose domains to risks of both lame delegation [1] and management hijacking. The draft includes descriptions of current known practices and suggests that some should be avoided, some are candidates for "best", and there are others that haven't been used that might also be candidates for "best". The authors would like to learn if others agree with our assessments and/or can suggest improvements. Please help. ICANN's SSAC is also looking at this issue and expert opinions will help us improve DNS resolution resilience. I plan to mention this quickly at IETF-117 given that the WG agenda is already full, but on-list discussion would be extremely valuable.
