 *  bool shared: false
 * }).
 * ...
 * If an IP version 6 (IPv6) address is used, both IP version 6 (IPv6) and
 * version 4 (IPv4) connections will be accepted. To restrict this to version 6
 * (IPv6) only, use v6Only to set version 6 only.
 * However, if the address is InternetAddress.loopbackIPv6, only IP version 6 
 * (IPv6) connections will be accepted.
 * @description Checks that if the address is InternetAddress.loopbackIPv6, then
