This traceroute tool tries to find out in various ways where each hop along the path is located and visualizes that on a google 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.
