 null.  <p>

 Hosts are considered equal if the names are equal (case independent)
 or if host name lookups for them both succeed and they both reference
 the same IP address. <p>

 Note that URLName has no knowledge of default port numbers for
 particular protocols, so "imap://host" and "imap://host:143"
 would not compare as equal. <p>

 Note also that the password field is not included in the comparison,
 nor is any reference field appended to the filename.</div>
