<div class="textblock"><p>Name and service resolution class. </p>
<p>This class provides support for doing name-to-binary resolution for nodenames and service ports. You should use this class if you need specific resolution techniques when creating a socket or if you want to inspect the results before calling the socket functions.</p>
<p>You can either create an object and set the options you want in it or you can simply call the static member functions, which will create standard Resolver objects and dispatch the resolution for you. Normally, the static functions will be used, except in cases where specific options must be set.</p>
<p>A Resolver object defaults to the following: </p>
<ul>
<li>address family: any address family </li>
<li>socket type: streaming socket </li>
<li>protocol: implementation-defined. Generally, TCP </li>
<li>host and service: unset</li>
</ul>

<p>In order to prevent simple mistakes in International Domain Names (IDN), it has been decided that certain code points (characters in Unicode) would be instead converted to others.

<p>For instance, the German 'ß' will be changed into 'ss', while the micro symbol 'µ' will be changed to the Greek mu 'μ'.</p>
<p>Two equivalent domains have the same normalised form. And the normalised form of a normalised domain is itself (i.e., if d is normalised, the following is true: d == normalizeDomain(d) )</p>
