  address mask
  subnet mask
  
     <networking> (Or "subnet mask") A bit mask used to identify
     which bits in an IP address correspond to the network address
      and subnet portions of the address.  This mask is
     often referred to as the subnet mask because the network
     portion of the address can be determined by the class
     inherent in an IP address.  The address mask has ones in
     positions corresponding to the network and subnet numbers and
     zeros in the host number positions.
