Detailed explanation-1: -Each time a packet takes another hop, its TTL is reduced by one. The TTL number that ping reports is the packet’s final TTL when it reaches its destination. To find out the number of hops a packet takes, subtract its initial TTL (by default 255) from the TTL reported by ping.
Detailed explanation-2: -Time to live (TTL) refers to the amount of time or “hops” that a packet is set to exist inside a network before being discarded by a router.
Detailed explanation-3: -By default, in Windows and many other OS’s, the TTL will be 128-that means that after a packet passes through 128 routers, if it hasn’t reached it’s final destination yet, the packet will expire and will be removed from the network.
Detailed explanation-4: -In networking, TTL prevents data packets from moving across the network indefinitely. In applications, TTL manages data caching and boosts performance. TTL is also used in other contexts, such as content delivery network caching and domain name system (DNS) caching.
