An <strong id="EN-US_TOPIC_0000001098670828__b842352706194051">inet</strong> value can be cast to <strong id="EN-US_TOPIC_0000001098670828__b84235270619412">cidr</strong>. After the conversion, any bits to the right of the subnet mask are silently zeroed to create a valid <strong id="EN-US_TOPIC_0000001098670828__b842352706194115">cidr</strong> value. In addition, you can cast a text string to <strong id="EN-US_TOPIC_0000001098670828__b84235270615826">inet</strong> or <strong id="EN-US_TOPIC_0000001098670828__b84235270615832">cidr</strong> using normal casting syntax. For example, <strong id="EN-US_TOPIC_0000001098670828__b84235270695824">inet(expression)</strong> or <strong id="EN-US_TOPIC_0000001098670828__b84235270695822">colname::cidr</strong>.</p>
