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.

Abstract: Provided are apparatuses and techniques for use by a first node on a network in determining the geographic location of a second node on the network. A data packet is received over the network from the second node, the data packet including a network identifier for the second node. Then, multiple probe packets addressed to the network identifier for the second node are sent, each of the probe packets being sent without waiting for a response from any previous probe packet.

Abstract: A database is populated with geographic locations for network devices by providing a node on a network and making a connection into a network service provider (NSP) point of presence (POP) to obtain a connection to the network via the NSP. A message is then transmitted to the node over the network connection obtained from the NSP. The message is received at the node and a source network identifier is extracted from the message. The source network identifier is then associated with a known geographic location for the POP in a database. The foregoing steps are then repeated for multiple different POPs. Also, a database is populated with geographic locations for network devices by providing a node on a network and making a connection into a network service provider (NSP) point of presence (POP) to obtain a connection to the network via the NSP. A message is then transmitted to the node over the network connection obtained from the NSP.
