- for Landmark_HostName see http://www-wanmon.slac.stanford.edu/cgi-wrap/reflector.cgi?function=landmarks in some cases the HostName is the same as IP
The From landmarks drop down list is populated from
- /nfs/slac/g/net/pinger/tulip/from.txt .
Design
The tabular traceroute is shown together with the Autonomous System Number (ASN), if known, the router's location coordinates and distance between hops. Clicking on the IP address will take you to the TULIP geolocation utility. Clicking on the ASN will provide information on the ASN. The From landmarks drop down list is populated from /nfs/slac/g/net/pinger/tulip/cachetr/from.txt .
Two traceroute paths are shown on the google map. One (shown in red) is drawn using TULIP and the other (shown in blue) is drawn using MaxMind (an IP host location database). The hops are shown as appropriate numbered markers, the error in the estimated location is shown as a red circle. See the figure below:
