The IESG has received a request from the Registration Protocols Extensions WG (regext) to consider the following document: - 'Registration Data Access Protocol (RDAP) Object Tagging' <draft-ietf-regext-rdap-object-tag-03.txt> as Best Current Practice The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-06-19. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Registration Data Access Protocol (RDAP) includes a method that can be used to identify the authoritative server for processing domain name, IP address, and autonomous system number queries. The method does not describe how to identify the authoritative server for processing other RDAP query types, such as entity queries. This limitation exists because the identifiers associated with these query types are typically unstructured. This document updates RFC 7484 by describing an operational practice that can be used to add structure to RDAP identifiers that makes it possible to identify the authoritative server for additional RDAP queries. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-regext-rdap-object-tag/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-regext-rdap-object-tag/ballot/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references.
