This object determines the mask of wild card address bits for caAclIPV4ACLDestinationAddress. Wild card masking is to indicate to the system whether to check or ignore the corresponding IP address bits when comparing the address bits in an ACE to a packet being submitted to the ACE. The default wild card mask is 0.0.0.0. The wild card mask is the inverse of a regular subnet mask. If the mask value 0.0.0.255 is applied to the address 1.2.3.4, it will match all traffic from subnet 1.2.3.0.
