No, it means the life time of a packet is 255 hops, everytime a packet traverses a router the TTL will be decremented by 1. This stops packets that are stuck in a routing loop endlessly bouncing around and taking up resources.
The end station or source will set the TTL.
Routing Protocols have there defination of HOP count not TTL, which is from source of that router to a destination, this does not equate to TTL in the IP header.
This thread refreshes my memory that my client asking why he would get a TTL value of large range when pinging different devices on his LAN - say routers and PC's normally being larger(2XX) but voice gateways being much smaller (XX), so can I say TTL value is specifically determined by the device itself(the firmware inside?) and the protocol o(TCP/IP ?) will modifiy packets with such information..
