This object determines the mask of wild card address bits
for caAclIPV4ACESourceAddress. 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 ACL
to a packet being submitted to the ACL. 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
1.2.3.0.
