Because it didnt reach the client in time hence useless.
A packet is a piece of data sent and received by servers and computers.
The Surprise Packet - 1913 is rated/received certificates of: UK:U
The receiver acknowledges packets it has received, and if the sender doesn't get an acknowledgment, it will eventually re-send the doubtful packet
if the MAC address is not matched, then the packet is discarded and not processed.

Data is transmitted in packets. TCP/IP has to respond to each packet. TCP allows for the sending side to know that the packet was received. If there is a malfunction, it can retransmit the packet.

That depends on the protocols used. TCP provides reliability, but if TCP is not used, higher-level protocols can include the reliability instead. That is to say, if a packet is not received, the higher-level protocol will take the responsibility of sending (or requesting) the packet again.For example, TFTP (Trivial File Transfer Protocol) uses UDP, and automatically resends a packet when an acknowledgement is not received after a certain time.That depends on the protocols used.

The delivery of Packet byDestination Computerin TCP\IP stack is reported by sending Acknowledgement to the Source Computerfor the received Packet by Destination Computer.
1.The router will discard the packet. 2.The router will send a time exceeded message to the source host.
number of hops
Your loop-back address or localhost is always 127.0.0.1. When a packet is sent to this address, the packet is routed internally to the network loopback device. The packet is then received back by your computer as if it came from an outside source.
