the packet before discarding and expiring the data (packet). TTL values are different for different Operating Systems. So, you can determine the OS based on the TTL value. You can get the TTL value by pinging an address. Here is the output got by pinging “subinsb.com” on my system ...
TTL is a timer value included in packets sent over TCP/IP-based networks that tells the recipients how long to hold or use the packet or any of its included data before expiring and discarding the packet or data. Folloing are the list of Devices / Operating system with Default TTL values...
and each router hop will decrease TTL Value by 1. This is actually helpful for network/security analysts to understand which Operating system is running on remote machine. Here is some output from my home lab: 1. Ping to Default gateway router (Cisco IOS) VPCS-1> ping 10.1.1.1 84 ...

The operating system sets the initial TTL value or application creating the IP packet. Here are some common default TTL values: Linux/MAC OS– 64 Windows– 128 Cisco Routers– 255 DNS– depends on the DNS resolver (can range from 128 to 86400) ...
