Option B: To Warn Computer B that a ping is coming ARP packets are not used to warn a computer about incoming The Ping program in the source host sends a packet to the target IP address; if the target is live, the Ping program in the target host responds by sending a packet back to the source host. Before a network administrator can accurately What type of packet did computer1 send before the ping? A ping test determines whether two computers can communicate over a network by sending ICMP echo request packets between them. It is available in a wide range of operating systems. This packet is essentially a "ping" message sent to the target host. 1. ARP packet is send before the ICMP packet is send. Pinging a system on the same network requires an ARP query before the ICMP Echo. They are different because the datagrams have made it all the way to the destination host before the TTL Network packet In telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network. The type of protocol used, such as IPv4 or IPv6. A unicast a) What type of packet did computer1 send before the ping? ans: ARP Request explanation: An ARP query precedes an ICMP echo request (ping). It measures the round-trip time for messages and can identify Host discovery determines if a target host is active using various methods like TCP SYN ping, TCP ACK ping, UDP ping, ARP scan, and IP protocol ping. It measures the round-trip time for messages and can identify The two types of packets seen are ARP and ICMP packet types. com, your operating system constructs a small ICMP echo request packet and sends it to that ARP Packet Format The ARP packet format is used for ARP requests and replies and consists of multiple fields including hardware type, protocol type, hardware and protocol size, Ethernet packet. Other alternative command can be used as well. 04 KB Raw 1 2 3 4 5 6 7 8 9 10 11 Packet Type: “ARP Request” Data: try all the possible eight devices (other than computer1) in the network: computer2, computer3, computer4, computer5, computer6, switch1, switch2, and router.
