Property Value

The value represents a DNS computer name, e.g. "domain.com", "example.microsoft.com", or "135.5.33.19". The property value can be any string, but not all values make sense and will work when an operation using them is attempted. Under normal conditions, host names are not empty, and they do not contain specific disallowed characters (",~:!@#$%^&'(){} ").

This value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

Remarks
The Host property contains the fully qualified DNS host name or IP address of the server.

The getter method of this property is pure, i.e. it does not have observable side effects.
