The TimeToLive property indicates the lifespan of the ping packet in seconds. This is an upper limit and not absolute as all routers MUST decrement this value by one and hops between routers rarely take this amount of time.  When this value becomes zero the packet will be dropped by the router. The default value is 80 seconds.
