With reference to the traceroute above the node so-3-0-0.mp1.Berlin1.Level3.net (4.68.128.42) is in Germany, Europe considering the Round Trip Times (RTT) from the following monitoring nodes:

From

RTT

Stuttgart, Germany

14 ms

Karlsruhe, Germany

20 ms

However, Geoiptool suggests that the node is in US, Kansas. IP2Location suggests that its in Washington, DC.

 TULIP suggest that it is somewhere in Europe: (though it locates in Norway my hunch is that its somewhere closer to the intersection of the 4 circles)

Incorrect result II

Similarly the node ae-1-0.bbr2.Dusseldorf1.Level3.net (212.187.128.21) is in Germany considering the following RTTs:

From

RTT

Karlsruhe, Germany

8 ms

Stuttgart, Germany

13 ms

Zurich, Switzerland

13 ms

Warrington, UK

13 ms

London, UK

14 ms

Where as IP2Location suggests that its in UK and so does Geoiptool.
