An apparatus, comprising: a processor; and a memory, at least one of the processor or the memory being adapted for: obtaining a packet, the packet including an IP source address and an IP destination address; composing a compressed access list key, at least in part, from 1) a modified IP source address that has been generated from the IP source address but excludes a subset of bits from the IP source address and that includes a first Zone_ID replacing the subset of bits from the IP source address such that the modified IP source address includes fewer bits than the IP source address and/or from 2) a modified IP destination address that has been generated from the IP destination address but excludes a subset of bits from the IP destination address and that includes a second Zone_ID replacing the subset of bits from the IP destination address such that the modified IP destination address includes fewer bits than the IP destination address; and routing the packet using the compressed access list key.
