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. The message is received at the node and a source network identifier is extracted from the message. The route over the network between the node and the POP is then probed to obtain network identifiers for routers along the route. The foregoing steps are then repeated for multiple different POPs.
