Class Description:
IP Address classes. Winsock is required to be initialized for this
to work.
Public Interface:
CIPAddress : Various constructors
operator = : Assignment operator
operator == : Comparison operators
operator const DWORD : Cast operator
operator LPCTSTR : Cast operator
operator CString : Cast operator
CompareItem : Comparison function
QueryIPAddress : Get the ip address value
QueryNetworkOrderIPAddress : Get the ip address value (network order)
QueryHostOrderIPAddress : Get the ip address value (host order)
StringToLong : Convert ip address string to 32 bit number
LongToString : Convert 32 bit value to ip address string
