Green line = high confidence in both endpoints Yellow line = high confidence in one endpoint; moderate confidence in other Blue line = moderate confidence in both endpoints Red line = geographic center of the country where the IP address is believed to be located, or the location obtained from the whois record of the associated domain name (Mapping2): Colored ball indicates the data source used for the lat/long mapping Green = DNS LOC record Yellow = Match found in GTrace DBs or user DBs Blue = Domain parsing file Cyan = Hostname reduction match Red = WHOIS record of the best-match domain name for IP address Gray = Country code (Mapping3): Color of RTT value shows how many packets were lost: Black = none Blue = lost one pkt Red = lost 2 or 3 pkts Visualization Tools: (Tool1) traceroute by Van Jacobsen (Tool2) GTrace java code by Ram Periakaruppen (CAIDA).
