 * full hostname has at least two dots, the function returns the join of the last three
 * parts. In all other cases, the function returns the last two parts of the hostname.
 *
 * @param {string} url - the url in question
 * @param {ex_SDLs} exceptionSLDs - the JSON list of second-level-domain exceptions
 * @returns {string} the domain name without subdomain
