    BSTR** pbstrIPMask
);

Parameters

bstrIPMask
BSTR that specifies the IP mask of the subnet.
pbstrIPMask

Visual Basic

Property IPMask As String

Property Value

String that specifies the IP mask of the subnet.

Remarks

This property is read/write.

The subnet mask is specified in this property as a string in dotted-decimal format. Its binary value should consist of a series of ones followed by a series of zeros. These series of bits separate the IP address specified in the IPAddress property into two parts. The first part becomes a network address, and the bits of the second part are reserved for all of the possible host addresses in the network segment.

The subnet mask typically consists of zero, one, two, or three binary octets that are represented in dotted-decimal format by the decimal number 255 and one binary octet that contains a series of ones (which may be empty) followed by a series of zeros and is represented by one of the following decimal numbers:
