By providing both VTrace (red) and Maxmind (blue)  routes, the results can be complementary in ascertaining the correct route. This is illustrated in the plots below from SLAC to a host in Braga Portugal (193.136.19.13). The left hand map shows how  VTrace accurately traces the route across the US, while Maxmind jumps from SLAC to the middle of the US, back to Berkeley and thence to Europe. This is shown in more detail in the W. Coast US map. Moving futheright, Vtrace shows the route through the Netherlands and the UK, while Maxmind  misses the Netherlands altogether. The Portugal detail indicates that Maxmind is more accurate in showing the final route to Braga. However, note that the Vtrace accuracy circles indicate the considerable uncertainty in the location of the last hop, hence improving ones confidence.  The traceroute figure which indicates that hops 12 and 13 are likely to be in the Netherlands and the UK given their naming conventions (note the top level domains .nl and .uk in the names). The TULIP plot shows how the  paucity of nearby landmarks (black market balloons) results in the poor geolocation of the Braga site.

Maxmind catches hop (8) in Europe (but gets hops 8 and 9 in London rather than Amsterdam) that VTRace (hop 8 does not respond to pings) misses and undns (orange line) misses both hops 8 and 9. VTRace catches the Johannesburg hop (4), and Pretoria hops (5) that undns and Maxmind miss. VTRace and undns catch the New York hop (10) that Maxmind misses.

Other Visual Traceroutes

  • CQ Traceoute, one server in St Paul, Minnesota, gives country, lat/long and distance of router from server, shows map as static image
  • DNSTools, one server in Frankfurt, no lat/long, provides map 
  • WhatismyIPaddress, only takes IP addresses, tabular output identifying city, map shows end point only
  • Montis, has 3 servers, in US (Pacific Northwest), Europe (Ireland) and Asia/Pacific (Singapore), provides map, no lat/longs or cities
  • Visualware, can choose server region and a limited number of target regions, requires Java, does not support traceroutes
  • VisualRoute, buy application, identifies city,  no lat/longs. no map
  • Free Visual, download free application, don't see a map
  • GTrace, download free application, has map
  • VTrace multiple servers, gives lat/long plus error, provides map,city, country code
