Default TTL - Time to Live

Time to Live - TTL

The lifetime of a data packet is determined by a default value. Why does a data packet have a lifetime?
So that a data packet is not endless in the network on the way or herumgeistert, it has a preset life.
Because at some point a data packet should also have reached its destination (desktop / server).
The default value is 64, so a data packet can be passed on a maximum of 64 times (hops).

The values ​​32, 64 and 128 are used values. To change the value, we use the following setting option:

We open the registry editor and go to the path: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters

See attachement. The key DefaultTTL with the value 64 is standard.
