Hi all, Following a few off-list discussions, I’m going to hold on including the root in the DNS bootstrap file at this time.
The intention is to enable RDAP clients to be able lookup the contact information for TLDs, as suggested or implied by the following sentence in RFC9224, Section 4. The entry for the root of the domain name space is specified as "". However, a client following the matching text earlier in that section will never match the root entry when there exists a TLD in the bootstrap file. This is because the longest-match rules will have the query for “com” matching the entry for “com”, and not the entry for “”. I’d say the matching logic is arguably incorrect – matching should begin with the parent of the supplied domain name. However, I acknowledge this arguably affects only queries for TLDs themselves, as a TLD’s RDAP server could redirect down to a more specific registry where necessary. A second consideration is that the root entry will match domains where there is no published RDAP server for that TLD. This will affect the behaviour described in RFC 9224, Section 7 Non-existent Entries or RDAP URL Values provides. I’m interested in your thoughts to whether the matching logic needs updating, and whether guidance or changes to the bootstrap file can reduce lookups for “non-existent entries” to the root, e.g. publishing an empty RDAP URL for delegated TLDs.

We do not yet have a date for this change and are currently looking to understand potential impact to RDAP clients. Hi James, Thanks for letting us know. <me as an RDAP mobile app developer> Would it be possible to share the targeted file so that implementations can be tested against it before it goes out? </me> Regards, Marc. Please reach out to me with any questions or comments. Note, the entry for the root of the domain name space is specified as "" [RFC 9224].
