ICMP, Internet control message protocol
sends messages between network nodes regarding the health of the network. Also informs about rerouting in case of errors. Utility PING uses ICMP messages to check physical connectivity of the network machines IPX, Appletalk, and NetBEUI are non-IP protocols. IP, Internet protocol - all hosts have an IP address. Each data packet has an IP address of sender and recipient. Routing in network is based upon these addresses. Datagram service is considered unreliable because there's no guarantee that the packet will be delivered, not even that its delivered only once and no guarantee that its delivered in the same sequence that its sent 32 bits long, IPv6 is 128 bits long

X is used for normal pings, as well as Pings of Death. Ping of Death describes attacks that were used to overflow poorly implemented ICMP handlers; smurf attacks, which spoof broadcast pings to create huge amounts of traffic on a network; and ping floods, which are a type of denial-of-service attack.
