A new Request for Comments is now available in online RFC libraries. BCP 221 RFC 8521 Title: Registration Data Access Protocol (RDAP) Object Tagging Author: S. Hollenbeck, A. Newton Status: Best Current Practice Stream: IETF Date: November 2018 Mailbox: shollenbeck@verisign.com, andy@arin.net Pages: 13 Characters: 22381 Updates: RFC 7484 See Also: BCP 221 I-D Tag: draft-ietf-regext-rdap-object-tag-05.txt URL: https://www.rfc-editor.org/info/rfc8521 DOI: 10.17487/RFC8521 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 and that makes it possible to identify the authoritative server for additional RDAP queries.
