<h3 id=urlhost-class>URLHost class</h3>

<pre class=idl>
[Exposed=*]
interface URLHost {
constructor(USVString host);

readonly attribute URLHostType type;

stringifier USVString toJSON();
};

enum URLHostType { "ipv4", "ipv6", "domain" };</pre>

<p>Each {{URLHost}} object has an associated <dfn for=URLHost>host</dfn> (a <a for=/>host</a>).

<hr>

<p>The <dfn constructor for=URLHost><code>URLHost(<var>input</var>)</code></dfn> constructor steps
are:

<ol>
<li><p>Let <var>host</var> be the result of <a>host parsing</a> <var>input</var> with true.

<li><p>If <var>host</var> is failure, then <a>throw</a> a {{TypeError}}.

<li><p>Set <a>this</a>'s <a for=URLHost>host</a> to <var>host</var>.
</ol>

<p>The <dfn attribute for=URLHost><code>type</code></dfn> getter steps are:

<ol>
<li><p>If <a>this</a>'s <a for=URLHost>host</a> is an <a>IPv4 address</a>, then return
"<code>ipv4</code>".

<li><p>If <a>this</a>'s <a for=URLHost>host</a> is an <a>IPv6 address</a>, then return
"<code>ipv6</code>".

<li><p>Assert: <a>this</a>'s <a for=URLHost>host</a> is a <a>domain</a>.

<li><p>Return "<code>domain</code>".
</ol>

<p>The <dfn for=URLHost>stringification behavior</dfn> and
<dfn method for=URLHost><code>toJSON()</code></dfn> method steps, are to return <a>this</a>'s
<a for=URLHost>host</a>, <a lt="host serializer">serialized</a>.
