Function Documentation

BYTE IPConvertMaskToSubnet

(

BYTE *

MaskArray

)

This function converts the long IP subnet expression to the CIDR expression.

Examples for subnet expression relations:

CIDR	Netmask
/8	255.0.0.0
/12	255.240.0.0
/16	255.255.0.0
/20	255.255.240.0
/24	255.255.255.0
/30	255.255.255.252

This function is added for MoBaCon projects.

Todo:

Add the (DWORD) output values.

Todo:

Move this function to the helpers.

Parameters:

MaskArray

The subnet as long IP expression (i.e {255,0,0,0}).

Returns:

The subnet mask as CIDR expression.

DWORD IPConvertSubnetToMask

(

BYTE

Subnet

)
