026 * <p><b>Domain name</b> validation routines.</p>
027 *
028 * <p>
029 * This validator provides methods for validating Internet domain names
030 * and top-level domains.
031 * </p>
032 *
033 * <p>Domain names are evaluated according
034 * to the standards <a href="http://www.ietf.org/rfc/rfc1034.txt">RFC1034</a>,
035 * section 3, and <a href="http://www.ietf.org/rfc/rfc1123.txt">RFC1123</a>,
036 * section 2.1. No accommodation is provided for the specialized needs of
037 * other applications; if the domain name has been URL-encoded, for example,
038 * validation will fail even though the equivalent plaintext version of the
039 * same name would have passed.
040 * </p>
041 *
042 * <p>
043 * Validation is also provided for top-level domains (TLDs) as defined and
044 * maintained by the Internet Assigned Numbers Authority (IANA):
045 * </p>
046 *
047 *   <ul>
048 *     <li>{@link #isValidInfrastructureTld} - validates infrastructure TLDs
049 *         (<code>.arpa</code>, etc.)</li>
050 *     <li>{@link #isValidGenericTld} - validates generic TLDs
051 *         (<code>.com, .org</code>, etc.)</li>
052 *     <li>{@link #isValidCountryCodeTld} - validates country code TLDs
053 *         (<code>.us, .uk, .cn</code>, etc.)</li>
054 *   </ul>
055 *
056 * <p>
057 * (<b>NOTE</b>: This class does not provide IP address lookup for domain names or
058 * methods to ensure that a given domain name matches a specific IP; see
059 * {@link java.net.InetAddress} for that functionality.)
060 * </p>
