Match between columns
                        Premises: A malformed ping using ICMP is sent to the victim's computer that exceeds the size of an IP packet
Functions by exchanging management information between networked devices
An attacker can use ICMP messages as one of the first steps in reconnaissance to discover information about the hosts that are part of the network
Substitutes addresses so that the computer is automatically redirected to another device
Attackers can broadcast a ping request to all computers on the network but change the address from which the request came to that of the target
Using a data-based OP network to add digital voice clients and new voice applications onto the IP network
Used by devices to communicate updates or error information to other devices
