Remote Traceroute Test
The free Dotcom-Monitor traceroute tool is an advanced service for troubleshooting network-related problems such as outages, poor network performance, or Border Gateway Protocol (BGP)-related problems.
The Intelligent Traceroute Service investigates the network connection between the monitoring agent and a user-specified destination host. After the service determines the address of each network hop between machines the service sends a sequence of 10 ICMP ECHO requests to each machine, to determine the response time of the link to each hop.
