RE: [IMRG] Help us test GeoLIM
The idea is great. I would like to use it to find hosts
that are hard to find and/or to verify conceptions of where hosts are located
(e.g. using the TLD or http://www.ip2location.com/ or whois
etc.) However, so far it has not worked well for me. My guess is that I am
trying to find hosts in Africa, S. Asia and S. America and you have few
landmarks that cover these regions. This may be deliberate since you mention
planetLab. However, it reduces the usefulness of the tool. I may be able
to help with providing landmark sites in Africa, Pakistan, Bangalore, Brazil
which might improve your accuracy and help me get better localization. Contact
me (off the list) if interested.
Dear Colleague,
We are developing the
GeoLIM project (
http://planetlab-01.ipv6.lip6.fr:10000/cbg.php) which
aims at
providing the
geographic location of an
Internet host based solely
on its IP address. The key element of
GeoLIM is its ability to transform delay measurements between landmarks
(probe machines) and a target host into geographic distance constraints. It uses
multilateration - like GPS - to estimate the geographic location of the
target host.
We're
seeking your help. We
ask you to test the geolocation solution through the
web page. This will take you no more than 3 minutes!
In particular, we are looking for
people to test the accuracy of our methods on various host types. For instance, with the same IP
address, estimate your location when you access the internet through a low or
high-speed line (telephone or DSL/LAN).
We're also looking for more
Landmark nodes (nodes used to provide the coordinates of
the system
). Therefore, we need the name of the node
and its latitude/longitude.
We'
d be glad if
you could provide us with
the name and location
of such a host.
Do not hesitate to distribute this mail to
colleagues interested.
The test is carried out on Planetlab (
http://www.planet-lab.org/).
We thank you for your
contribution. More details about our algorithm can be found at (
