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.

If you would like to test for DNS issues, visit www.dotcom-monitor.com/WebTools/trace.asp and select Trace Style: DNS.

Dotcom-Monitor also offers ongoing DNS Monitoring as part of an external SaaS model. For more information, visit www.dotcom-monitor.com/dns-monitoring.asp.

UltraDNS is a managed DNS service owned by Neustar. They handle over 14 billion DNS queries daily.
