ABSTRACT:
Provided are techniques and apparatuses for determining the geographic location of a node on a network. In a representative embodiment, a data packet is received over the network from a second node, the data packet including a network identifier for the second node and a Time-To-Live (TTL) field that has a value, with the value of the TTL field for the data packet indicating a maximum additional number of hops that could have been made by the data packet. A probe packet addressed to the network identifier for the second node is then sent, the probe packet also including a TTL field. The initial value for the TTL field of the probe packet is set based on the value for the TTL field of the data packet.
