Ping Test Setting
TraceRoute Tests
The Internet is a complex aggregation of network hardware connected by gateways. Tracking
the route packets follow or finding a gateway where the packets are being discarded is
difficult. The Trace Route test attempts to trace the route an IP packet follows to a specified
Internet host. This test utilizes the Time To Live (TTL) field in the IP header to allow
intermediate nodes to be "discovered" via Internet Control Message Protocol (ICMP).
Intermediate hops are discovered by launching probe packets with a small TTL and then
listening for an ICMP Time Exceeded reply from a gateway. Use
