<h3><a name="IceSupportforIPv6withinProxies-Configuration"></a>Configuration</h3>
<p>By default Ice is not configured to support IPv6. To enable it the following configuration option must be passed to the runtime (usually via configuration file).</p>
<div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent">
<script type="syntaxhighlighter" class="toolbar: false; theme: Confluence; brush: java; gutter: false"><![CDATA[
Ice.IPv6=1
]]></script>
</div></div>
<p>This will allow proxies containing IPv6 endpoints to be created and also for received proxies containing IPv6 endpoints to be used.</p>
<p>Please note that if no host is specified when configuring an object adapter's endpoints then all addresses on the machine will be added as endpoints. This means that a proxy will contain both IPv4 and IPv6 addresses if the machine is configured with them.</p>
<h3><a name="IceSupportforIPv6withinProxies-MixedEnvironments"></a>Mixed Environments</h3>
<p>If operations are invoked on a proxy that contains endpoints with differing address families then, by default, a random endpoint will be chosen unless a connection is already up.</p>
<p>If operations are invoked on a proxy that contains endpoints with differing address families then only endpoints with supported address families will be considered.</p>
<p>If operations are invoked on a proxy that contains endpoints with only unsupported address families then an Ice::DNSException exception will be thrown.</p>
