This plug-in is used to skip other plug-in instances when processing DNS requests.
This is typically used to apply one or more conditions (in the "DNS Requests" tab) to several other plug-ins at the same time.

Instead it instructs Simple DNS Plus to skip some or all of the following plug-in instances (listed in the Simple DNS Plus Options dialog / Plug-Ins section) - when the conditions in the "DNS Requests" tab are met.
To setup a new Skip plug-in instance; in the Simple DNS Plus Options dialog / Plug-ins section, select the "Skip" component and click the "Create new instance..." button.
