Configuration Settings
The TraceRoute component allows you to trace the path IP packets
take on the Internet.
NOTE: What follows is a very short description of the component interfaces.
For more information, please consult the help files that come with the respective package.
Remarks
The component implements a standard IP Traceroute as defined in RFC 1393.
To use the component, simply call the TraceTo method and set the
Host parameter to the domain name or IP address of the host you
want to trace the path to. This is identical to setting the RemoteHost
property to the domain name or IP address. The component will start
sending probe packets towards the host, and as it receives replies it
will fire Hop events giving information about the route.
The same information is also provided in the Hops properties
.
The ResolveNames property enables or disables DNS
resolution of IP addresses received during the trace. If set
to False only IP addresses are provided. If set to True
the component will attempt to resolve the names of the
hosts in the route. This may considerably increase the time
it takes to complete the trace.
The HopTimeout property determines the maximum waiting time
for a response in each hop of the trace, while the Timeout
property defines the maximum waiting time for the whole trace.
The HopLimit property specifies the maximum number of hops
allowed for a trace.
