The England to Washington DC is interesting since VTrace, Maxmind and undns (orange line) give very different results for the target. Despite Sofia University advertising itself as being in Palo Alto the web server is actually near Washington DC. Also the route does not go from London to Paris as indicated by Maxmind.
For the Pakistan to hotmail.com (Microsoft WA) undns gets off track and goes to Australia. VTrace correctly gets hop 6 as being in Karachi (while Maxmind puts it in the middle of Pakistan), however VTrace loses track after getting to Franfurt Germany (since hops 9-13 do not respond to pings), while Maxmind gets the end destination as being Microsoft's home of Redmond Washington.
Complementarity of VTrace and MaxMind
...
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.
