Detailed Description

Internet addresses used specifically as masking addresses (such as " 255.255.255.0") are held in the IPV6Mask derived object.

The seperate class is used so that C++ type casting can automatically determine when an IPV6Address 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 IPV6Host operator& ( const IPV6Host addr,
const IPV6Mask 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.
