This is the wildcard mask for the
cippfIpFilterDestAddress bits that must match. 0
bits in the mask indicate the corresponding bits
in the cippfIpFilterDestAddress must match in order
for the matching to be successful, and 1 bits are
don't care bits in the matching. A value of zero
causes only IP packets of source address the same as
cippfIpFilterSrcAddress to match. This object value
has to be consistent with the type specified in
cippfIpFilterAddressType.
