CreateIPConfigSubnetMask Method—Creates an IP Address Configuration Based on the IP Address and Subnet Mask

The CreateIPConfigSubnetMask method creates an IP Address configuration based on the IP address and subnet mask passed to the method. For the policy to fire, a request must come from the subnet address derived from the passed IP address and subnet mask.

Syntax

The CreateIPConfigSubnetMask method has the following format:

Netegrity::PolicyMgtPolicy‑>CreateIPConfigSubnetMask(ipAddr, subnetMask)

Parameters

The CreateIPConfigSubnetMask method accepts the following parameters:

ipAddr (string)

Specifies the IP address used to derive the subnet address.

subnetMask (unsigned long)

Specifies the subnet mask used to derive the subnet address.

Return Value

The CreateIPConfigSubnetMask method returns one of the following values:

• A PolicyMgtIPConfig object
• undef if the call is unsuccessful

Remarks

The subnet mask value is a number of bits. To arrive at this value, count the bits in the binary value of the address. For example, suppose the subnet mask is 255.255.255.128. The binary format is:

11111111 11111111 11111111 10000000

Counting from left to right, the number to pass in subnetMask would be 25.
