THE CLASSIFICATION

A map of labels,
not a ranking.

Country-code status is inferred only from two-letter ASCII labels; internationalized entries are identified by their xn-- form. Everything else is presented as generic unless it is the DNS infrastructure label .arpa. No category implies quality, eligibility, price, or trust.
