Internet addresses used specifically as masking addresses (such as '
255.255.255.0') are held in the IPV4Mask derived object.
#include <address.h>
IPV4Mask (const char *mask)
Create the mask from a null terminated ASCII string such as '255.255.255.128'.
IPV4Address & operator= (unsigned long addr)
Allows assignment from the return of functions like inet_addr() or htonl().
__EXPORT IPV4Host operator& (const IPV4Host &addr, const IPV4Mask &mask)
Masks are usually used to coerce host addresses into a specific router or class domain.
Internet addresses used specifically as masking addresses (such as '
255.255.255.0') are held in the IPV4Mask derived object.
The seperate 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.

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.
