#### Check Result <a href="#hostnameintegritycheck-checkresult" id="hostnameintegritycheck-checkresult"></a>

#### Usage <a href="#hostnameintegritycheck-usage" id="hostnameintegritycheck-usage"></a>

The check is configured with the expected response (responses) as an input parameter.

The expected responses can be in IP Address, Subnet Mask or [CNAME](https://apica-kb.atlassian.net/wiki/pages/createpage.action?spaceKey=ASMDOCS\&title=CNAME\&linkCreation=true\&fromPageId=4635410) format.

When multiple expected responses are used, the check can match any one or all of them.
