I now what TTL is and how it works, but I can't figure out why it's different each time I do a ping.

For example, when I ping various servers on our network the TTL time can be either 127 for server A and 254 for server B.

Doing a tracert to server A, I get 2 hops, and same thing for server B. Not sure if that's relevant.

So is Server A a Windows box and Server B a different OS?

Seems that the Windows OS reduces the TTL from the starting value of 255 and subtracts 128 from it on the return trip. Linux subtracts 192 on the return trip. Each router along the path will decrement by one.
