This is the wildcard mask for the
cippfIpFilterSrcAddress bits that must match. 0 bits
in the mask indicate the corresponding bits in the
cippfIpFilterSrcAddress 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.
