How is the TTL (Time to Live) field utilized in IPv4?
What will be an ideal response?
ANSWER: The TTL field indicates the maximum duration that the packet can remain on the network before it is discarded. Although this field was originally meant to represent units of time, on modern networks it represents the number of times a packet can still be forwarded by a router, or the maximum number of router hops it has remaining.The TTL for packets varies and can be configured; it is usually set at 32 or 64. Each time a packet passes through a router, its TTL is reduced by 1. When a router receives a packet with a TTL equal to 0, it discards that packet and sends a TTL expired message via ICMP back to the source host.
