TTL=128

[gman10]

Can someone explain in detail what this means when doing a ping and good TTLS come back with this eg -

reply from 127.0.0.1: bytes=32 time<10ms TTL=128

what exactly does the TTL=128 depict?

thx

This time to live (TTL) is set to a specific number (in this case, ping packets get a TTL of 128).


So who cares right? Well, let me explain what happens to the TTL and how it can help you.
As the PING communication packet travels across the network, whenever the packet passes through a router or other network device, it decreases by one. (NOTE: it is possible, in the most severe cases, for the TTL to drop to a value of zero and then the packet is discarded by the router). In most cases, you can see that the TTL information can be used to determine approximately how many router hops the packet has gone through. (NOTE: TTL does not count the same device twice in standard traffic flow. This is not the case with routing loops).

Hope this helps..

Hi Chris77504 -

So when I do a ping and the IP address has a return TTL of 64 or 32 or 128.. what does that number at the end of the TTL response tell me? I'm still a bit confused over this..

thx
