1. A method, comprising:
detecting a packet handling device that performs network address translations between an originating device and a detection device; and
analyzing one or more transmission parameters of a packet received at the detection device to detect the packet handling device that performs network address translations, wherein analyzing further includes comparing a first transmission parameter of the one or more transmission parameters to a standard transmission parameter, wherein the packet handling device is detected if the comparison of the first transmission parameter is not equal to the standard transmission parameter, and wherein the first transmission parameter is a time to live (TTL) value and the standard transmission parameter is a standard TTL value.
