Hi there all, Back in 2018, I've mentioned that I've agreed to AD sponsor draft-cheshire-sudn-ipv4only-dot-arpa ( https://datatracker.ietf.org/doc/draft-cheshire-sudn-ipv4only-dot-arpa/ ), and asked for review / feedback.
When RFC7050 was written, the name 'ipv4only.arpa' was not requested to be added to the SUDN registry - regardless of if you think that RFC7050 is a good idea or not, having this properly recorded seems like an obvious win. I asked DNSOP (and the BEHAVE list) for review and input back in 2018. The authors have (finally!) posted a new version with some comments addressed, and I'm requesting IETF LC. Please send comments as usual (but, again, this isn't a discussion on the advisability of RFC7050, just on this document :-)) -------- Abstract The specification for how a client discovers its local network's NAT64 prefix [RFC7050] defines the special name 'ipv4only.arpa' for this purpose, but in its Domain Name Reservation Considerations section that specification indicates that the name actually has no particularly special properties would require special handling, and does not request IANA to record the name in the Special-Use Domain Names registry. Consequently, despite the well articulated special purpose of the name, 'ipv4only.arpa' was not recorded in the Special-Use Domain Names registry as a name with special properties. As a result of this omission, in cases where software needs to give this name special treatment in order for it to work correctly, there was no clear mandate authorizing software authors to implement that special treatment. Software implementers were left with the choice between not implementing the special behavior necessary for the name queries to work correctly, or implementing the special behavior and being accused of being noncompliant with some RFC. This document describes the special treatment required, formally declares the special properties of the name, and adds similar declarations for the corresponding reverse mapping names. ----- Thank you! W -- I don't think the execution is relevant when it was obviously a bad idea in the first place. This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
