Acquire a "public suffix" list, i.e., a list of DNS domain names reserved for registrations. Some country Top-Level Domains (TLDs) make specific registration requirements, e.g., the United Kingdom places company registrations under ".co.uk"; other TLDs such as ".com" appear in the IANA registry of top-level DNS domains. A public suffix list is the union of all of these. Appendix A.6.1 <https://tools.ietf.org/html/rfc7489#appendix-A.6.1> contains some discussion about obtaining a public suffix list. The point of the paragraph in question wasn't to define TLDs (or PSDs) but rather to better define "domain names reserved for registration". > > > 2.

The second paragraph could be rewritten as *The original design of DMARC applies only to domains that are registered with a domain name registrar (called “Organizational Domains” in RFC 7489) and nodes in the tree below Organizational Domains. Organizational Domains are themselves nodes in the tree below domain names reserved for registration, the latter of which will be referred to as Public Suffix Domains (PSDs) in this document.* But how to address Dale's concerns about how one knows all PSDs? -- Todd Herr
