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 |

Karlsruhe, Germany |
8 ms |
Stuttgart, Germany |
13 ms |
Zurich, Switzerland |
13 ms |
Warrington, UK |

Where as IP2Location suggests that its in UK and so does Geoiptool.
TULIP suggests that the router is in Netherlands which seems to more accurate:
