Abstract:
1. A method, the method comprising the computer-implemented steps of: detecting from one or more first network packets, an Internet Protocol (IP) address and a first Media Access Control (MAC) address; wherein the IP address and the first MAC address are used to determine that the IP address and another MAC address that are detected in one or more second network packets is an illegal binding and wherein said another MAC address is different from the first MAC address; causing a network element to create, in an address resolution protocol filter, based on the IP address and the first MAC address, one or more rules that cause the network element to prevent an address resolution protocol table from including a binding that includes only one of the IP address and the first MAC address; and in response to detecting the IP address and said another MAC address in the one or more second network packets, preventing the address resolution protocol table from including the illegal binding that includes the IP address and said another MAC address.
