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
