A. Submission Date: May 7th, 2024 B.1 Submission Type: [X] New RRTYPE [ ] Modification to RRTYPE B.2 Kind of RR: [X] Data RR [ ] Meta-RR C. Contact Information for submitter (will be publicly posted): Name: Scott M. Johnson Email Address: scott&spacelypackets.com International telephone number: +13868887311 Other contact handles: D. Motivation for the new RRTYPE application. Bundle Protocol (RFC 9171), specifies the "ipn" URI scheme (section 4.2.5.1.2) for use in naming nodes in Delay and Disruption Tolerant Networks (DTNs). This URI scheme is widely deployed among DTNs, and would benefit from having the capability to look up the CBHE Node Number (node-nbr) component (or successor standard) for a given node based on a domain name. https://www.iana.org/assignments/bundle/bundle.xhtml#cbhe-node-numbers E. Description of the proposed RR type. A record using the proposed RRTYPE would consist of one 64 bit integer, representing the CBHE Node Number component of the "ipn" URI of a given DTN node (RFC 7116), encoded in US-ASCII. Future amendments to the "ipn" URI scheme may modify the Node Number data structure, but given that the RRTYPE is to be processed as an "unknown RRTYPE" these amendments will be irrelevant to nameserver operation. F. What existing RRTYPE or RRTYPEs come closest to filling that need and why are they unsatisfactory? There are many RRTYPES which are similar and complementary in function to the proposed new RRTYPE, such as A, AAAA, X25 or ISDN. These are unsatisfactory due to incompatible data structures and the desire for disambiguity in the use of a particular RRTYPE. G. What mnemonic is requested for the new RRTYPE (optional)? IPN H. Does the requested RRTYPE make use of any existing IANA registry or require the creation of a new IANA subregistry in DNS Parameters? Other than the addition of the IPN RRTYPE to the existing "Resource Record (RR) TYPEs" IANA Registry, no modifications are required. I. Does the proposal require/expect any changes in DNS servers/resolvers that prevent the new type from being processed as an unknown RRTYPE (see [RFC3597])? No. J. Comments:
