Greetings, I am seeking the wisdom of the WG on the following.
Section 4 of RFC 9224 states that: (a) "the domain name's authoritative registration data service is found by doing the label-wise longest match of the target domain name", and also that (b) "the entry for the root of the domain name space is specified as "".". The upshot of this is that if IANA were to add an entry for the root to the bootstrap file, RDAP clients that implement RFC 9224 would hit the IANA server for *all* queries for domains under TLDs that haven't added their base URL to the bootstrap file. As of writing, that's about 25% of all registered domains[1]. I believe that this has significant implications on the privacy of user queries, in addition to the operational impact it would have on IANA. Sentence (b) above was introduced in draft-ietf-weirds-bootstrap-11[2], while that document was going through IETF last call. I haven't found the specific mailing list thread that resulted in its addition, but it seems unlikely to me that funnelling queries to IANA's RDAP server was the intent of the WG or the author, and that an errata would be appropriate. Thoughts? G.
