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 Frankfurt Germany (since hops 9-13 do not respond to pings), while Maxmind gets the end destination as being Microsoft's home of Redmond Washington.

Miscellaneous
Often the traceroute does not complete to the destination. An example is the traceroute from SLAC to UTM in Johor Bahru, Malaysia. It stops at hop 16. TULIP is able to locate pinger.fsksm.utm.my pretty accurately since there is landmark at the site, while GeoIPTool (Maxmind) locates it in Sarawak. However, VTrace
The traceroute from SLAC to UTM, Johor Bahru, Malaysia for MaxMind goes to central US, Japan, then via China and terminates in Sarawak. The VTrace goes from SLAC to Japan (undns confirms this), then to Kuala Lumpur Malaysia, then to Johor Bahru. It then takes an excursion to the Gulf of Thailand (hop 14) and appears to stop there (middle image below). On more detailed inspection (right hand image below), it is seen that it then returns to Johor Bahru and UTM (hops 15-16).

Looking in more detail at hop 14, only 4 landmarks have a minimum RTT of < 60ms. Three are in Thailand and one in Kuching Malaysia. See left image below. There are other landmarks in the area, one at UTM in Johor Bahra, Malaysia, another at UM in Kuala Lumpur. However, for unknown reasons neither UTM nor UM were able to ping 161.139.244.5.
