Visualization Thumbnail Evaluation Strengths:
(Strength1): Useful for identifying network topology and gaining macroscopic insight into Internet infrastructure. (Strength2): Useful for discovering potentially inefficient routing. Issues:
(Issue1): Can be slow.
(Issue2): Accuracy would be much improved if the Internet community maintained DNS LOC records, or a better NetGeo database was available.

Visualization Thumbnail About the Visualization Visualization Techniques:
(Technique1): Plot lat/long points; draw straight lines between hops. Key Visualization Mappings:
(Mapping1): Line color shows confidence in location mapping. 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:
