1) If you search \IP-ADDRESS you are not using DNS. You are using just straight routing and your Gateway is directing you to where you need to go. 2) By utilizing “sam@xyz.com”, then you are utilizing DNS to locate the nearest domain controller (if site and services configured) for the lookup of this request.
