Time-to-live (TTL) is a value for the period of time that apacket, or data, should exist on a computer or network before being discarded. The meaning of TTL, or packet lifetime, depends on the context. For example, TTL is a value in an Internet Protocol (IP) packet that tells a ...
Time to Live (TTL) is a computer networking term that refers to the lifespan of data on the network. TTL determines how long a packet stays alive before the router discards it. Setting the right TTL value is crucial for optimizing network performance and reliability. What is Time to Live?
Time Exceeded: Sent when a packet’s Time-to-Live (TTL) expires, commonly seen in traceroute applications. Redirect Message: Informs hosts of a better route to reach a destination. b. Query Messages Echo Request and Echo Reply: Used for diagnostic purposes, as in the popular “ping” comma...

It initially starts with a TTL of 1, so the first router receives the packet, decrements the TTL to 0, and drops the packet while sending an “ICMP time exceeded” message back.Going forward, traceroute increments the TTL for each packet that it sends. This means the next router that ...
