Hi Rick, As I have previously stated, I personally have lodged no objection to using CBOR encoding of (node-nbr) in this case, and actually mentioned the option myself. Here is the situation as I see it: I have requested the creation in the IANA database of the IPN and CLA RRTYPEs, by the means detailed in RFC6895, section 3.1.1; to whit, completed (twice, one for each) the form found in Appendix A. of same. My requests meet the criteria of part 2 of 3.1.1. I ran afound of section 3.1.2, point 1, as the Expert Reviewer explained that I needed to designate wire and presentation formats for the requested records, in Individual Informational internet-draft format. I produced that document, and, as suggested by Expert Reviewer, sent it to DNSOP for review. There, I received guidance on verbiage and optimal choice of formats from DNS expert Mark Andrews. I also consulted Scott Burleigh, first named author of RFC9171, for any particular BP related concerns. With the help of, and achieving concensus with these two learned individuals who possess significant specialized knowledge of the two systems we are integrating in the above described standardized process, we arrived at a viable document in several hours. Upon request of Transport AD, I forwarded to DTN. Of the productive responses received, Brian Sipos pointed out an interoperability problem with the notation I wove from whole cloth (based on the notation used in IPND) to describe CLAs, and you requested information concerning motivations of the document. Time being of the essense, I incorporated changes to address the point Brian made and added a section to text describing my motivation. I did so in short order, as I did previously with the consultations on DNSOP. You raised technical challenges to the proposed 64-bit integer wire encoding for IPN in this use case, citing RFC9171, and your own draft. Section 4.2.5.1.2 clearly defines the rules for encoding of EIDs. Only one component of EID is to be encoded in the RRTYPE, and hence, not an EID. Further, 64-bit integer is the preferred encoding of the DNS experts, and Scott Burleigh has confirmed that this proposal conforms to the encoding defined in your draft; an assertation which has not been refuted. It has also been confirmed that there is no conflict between the registration of these RRTYPEs in the described formats and the content of your draft. This particular encoding is not for use inside bundles or by BPAs; indeed, it will only appear (please correct me if i am wrong, DNSOP participants) internally inside nameservers and resolvers and on the wire between them. Thus, these technical challenges seem to have been addressed. An alternate proposal was put forward in theory, fulfilled in part by an expired draft by Brian Sipos, who has indicated that he does not have time to work on that solution at present. I believe him; I imagine his workplace is exceedingly busy of late. I know mine is. Having arrived at loose consensus with experts from both disciplines involved, and lacking a good reason to further revise the draft which is now before the Expert Reviewer for a decision as to the creation of the RRTYPEs, I think the best course of action is to let the Expert Reviewer do their job and approve or (hopefully not) deny the RRTYPE reservations. The IANA registry will likely reference my draft if approved, and I will likely be requesting at least one more RRTYPE to hold BPSEC data. If DTN WG wishes to take up this special purpose individual informational draft instead of other pressing business it is chartered for, it is free to do so. It is in no way necessary to do so to perfect my RRTYPE request procedure, and seems a waste of time to me. If you want something for the WG to take up, I will be producing another Informational draft soon which you will surely find interesting concerning discrete DNS networks on different planetary bodies interoperating by means of transiting IP request metadata across the BP deep space network. That, IMHO, is worthy of asking the attention of the group here assembled. Please understand; we are operating in an Adopt, Adapt, Author order of preference when it comes to solving real world problems being faced right now. In this case, 'Adopt'ing new DNS RRTYPEs to distribute BP information to IP speaking BP nodes fits the bill. It "just works" in a way that those who will use it will already understand, and is easy to implement all the way around. It may not be the best solution possible, but it was the best one available.
