Describe the TTL field in an IP packet header.
What will be an ideal response?
Time to Live (TTL)-This 8-bit value identifies the maximum amount of time the packet can remain in a network before it is dropped. Each router or device through which the packet passes (hops) reduces the TTL by a value of one. The TTL avoids congestion that results from corrupted packets infinitely looping through the network.
