    determining, using a processor in communication with the network port, whether the network packet should be assigned a shared public IP address or a dedicated public IP address, the determination being based at least in part on data relating to a host device associated with the network packet; and

    transmitting the network packet to an external network system, using communication parameters including either a dedicated public IP address if the network packet should be assigned a dedicated public IP address based on the determination, or a shared public IP address if the network packet should be assigned a shared public IP address based on the determination.
