This traceroute tool tries to find out in various ways where each hop along the path is located and visualizes that on a map.
This is done by querring the DNS for a "LOC" (RFC 1876) entry, if that
fails, a internal database table is used to determine the location via a regular expression on the hostname. When no entry is found,
a whois query on the IP-address is made to determine the location (City Name, Country) and the result is then translated to coordinates
with the help of a local database. If even that fails, it falls back to use MaxMind's GeoLight City Database.

In front of the traceroute lines you see a pargraph which represents the rtt
(round trip time) of a packet,
green is
minimum, red
is maximum and blue line is
the average time. Times over
200ms are not graphed correctly.
At the end of each row you have the georaphical informations the letter in
front of the braces is the lookup method that came to a result.
"D" stands for DNS LOC, "R" for Regular Expression, "W" for Whois and "N"
for MaxMind.
This lookingglass queries the OpenBGPd border router of FreeStone Systems (AS196621).

On this page you can check where geo ip services think the ip is located.

Look up the Vendor of the Card based on any MAC address or auto configured IPv6 address. We check against a local Database which gets updated daily from IEEE.

We have developed a small Web-Browser plugin which displays the AS number, IP Address and Country of the Webserver which runs the website you currently visit.
The Plugin runs in Firefox and Chrome. It is not widly tested yet. please contact me if you encounter any problems.
This is a complete rewrite from the old crossrider based version. Please Upgrade to the new version. You need to remove the old plugin by hand first and then install the new one.
The plugins are available from the official extension repositories of the reespective browser
