In one embodiment, a system includes a switching processor and logic integrated with the switching processor, the logic being configured to receive a packet, wherein the packet comprises a header and a payload, determine, without using a look-up table, a destination port based on a destination address stored in the header, and send the packet to the destination port. In another embodiment, a system includes logic integrated with and/or executable by a processor, the logic being configured to create an address allocation table comprising a plurality of values, each value being associated with a plurality of IP addresses which, when an algorithm is applied thereto, result in the associated value, receive a request for an IP address from a device electrically connected to a switch, and determine a port to which the device is electrically connected to the switch based on the port on which the request is received.
