Abstract: Disclosed are various embodiments of a network switch for storing a prefix address and a mask corresponding to the prefix address, the prefix address and the mask each representing a binary value, the mask representing a number of significant bits of an address beginning with a most significant bit. The network switch obtains a network frame via one of a plurality of network interfaces, the network frame comprising a network address in a header of the network frame, the network address being a binary value representing a physical address of a network interface device. The network switch determines a truth value associated with a comparison of a mask number of bits of the prefix and network addresses, the truth value indicating an equivalence of the comparison. In response to the truth value, the network switch may initiate at least one action associated with the network frame.
