NAME

       ost::IPV4Mask - Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are
       held in the IPV4Mask derived object.

           Allows assignment from the return of functions like inet_addr() or htonl()

           Masks are usually used to coerce host addresses into a specific router or class domain.

Detailed Description

       Internet addresses used specifically as masking addresses (such as ' 255.255.255.0') are held in the
       IPV4Mask derived object.

       The separate class is used so that C++ type casting can automatically determine when an IPV4Address
       object is really a mask address object rather than simply using the base class. This also allows
       manipulative operators for address masking to operate only when presented with a Masked address as well
       as providing cleaner and safer source.

   __EXPORT IPV4Host operator& (const IPV4Host & addr, const IPV4Mask & mask) [friend]
       Masks are usually used to coerce host addresses into a specific router or class domain. This can be done
       by taking the Inet Host Address object and 'and'ing it with an address mask. This operation can be
       directly expressed in C++ through the & operator.

       Returns
           a internet host address that has been masked.

       Parameters
           addr host address to be masked by subnet.
           mask inetnet mask address object to mask by.
