Console.WriteLine(" Forwarding enabled ...................... : {0}", ipstat.ForwardingEnabled)
Console.WriteLine(" Interfaces .............................. : {0}", ipstat.NumberOfInterfaces)
Console.WriteLine(" IP addresses ............................ : {0}", ipstat.NumberOfIPAddresses)

Remarks
The TTL value is reported as the number of routing nodes that can forward a packet before it is discarded. Each node decrements the current TTL value in a packet before forwarding it. If the TTL value reaches zero, the packet is deemed undeliverable and is discarded. Note that when a packet travels from one node to another, this is also known as a "hop".
