__EXPORT IPV6Host operator& (const IPV6Host &addr, const IPV6Mask
&mask)
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 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.
