So, given it exists, systems are coded to behave against it, and not having SOME ccTLD (and I would posit gTLD) on it, means they don't match as "first class citizens" the behaviour the PSL brings.
Actually, the PSL matching algorithm is such that all TLDs are considered public suffixes: | Match domain against all rules and take note of the matching ones. | If no rules match, the prevailing rule is "*". https://github.com/publicsuffix/list/wiki/Format#algorithm Thus, absent a negative rule that would declare a TLD a private suffix, the algorithm labels TLD suffixes public. However, there are no top-level exemptions defined: $ grep '^!' public_suffix_list.dat !www.ck !city.kawasaki.jp !city.kitakyushu.jp !city.kobe.jp !city.nagoya.jp !city.sapporo.jp !city.sendai.jp !city.yokohama.jp Peter -- https://desec.io/ _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
