That text says TLD .uk made decision so and so. It doesn't imply that .co.uk is somehow to be considered a TLD. That wikipedia page is questionable. https://en.wikipedia.org/wiki/Talk:Second-level_domain > The point of the paragraph in question wasn't to define TLDs (or PSDs) but > rather to better define "domain names reserved for registration".

Nevertheless, the concept of *Public Suffix* is independent of its only known implementation (and of some acceptations of the term "public"). It is the concept that 7489bis is going to craft. I propose to stick to the term Public Suffix, whatever its future definition is going to be. jm2c Ale -- _______________________________________________ dmarc mailing list dmarc@ietf.org https://www.ietf.org/mailman/listinfo/dmarc
