              "This object is used to qualify the value of the
               corresponding instance of snmpTargetAddrTAddress.
               The format of this object is determined by the
               corresponding instance of snmpTargetAddrTDomain.

               When performing transport address validation on
               a received packet, the value of this object is
               used as a mask to determine whether a source
               address matches a particular entry in the
               snmpTargetAddrTable.  In general, the comparison
               using this mask value is performed as follows for
               each octet contained in the source address and
               snmpTargetAddrTAddress value:
                   (sourceAddr & tgtAddressMask) ==
                      (snmpTargetAddrTAddress & tgtAddressMask)
               if the values are equal for all octets, the source
               address matches the entry."
