Traceroute Tool Description

Traceroute Modes

• ICMP echo request packets (generated by the Windows operating system, multithreaded)
• ICMP echo request packets (generated by WinPcap, multithreaded)
• UDP variable target port number packets (multithreaded)
• UDP fixed target port number packets (not multithreaded)
• TCP fixed target port number packets. (not multithreaded)

NetScanTools Pro enhancements to "classical" or command line Traceroute:

• Our multithreaded modes are very fast. For example, NetScanTools Pro completed an ICMP traceroute to netscantools.com in 4 seconds including resolution of all IP addresses to hostnames.
• Supports multiple tracing modes, ICMP, UDP, and TCP in one application.
• UDP Ping can have either fixed or variable target ports. The source port is always variable. Fixed target port mode is useful to trace through a target firewall that may have a specific UDP port open, perhaps the DNS port.
• TCP Traceroute. This specialized mode uses TCP SYN packets sent to the target.
• TCP and UDP source and destination ports are separately user-defined.
• TCP header fields are user defined and may also be randomly selected. These fields are Sequence, Window, and Acknowledgement.
• TCP packet options section for MTU is included and the value is user defined.
• The data portion of the payload for ICMP and UDP ping may be a simple 'a-z' repeating character string or the contents of any file you choose (binary or ascii).
• Retrieval of AS (autonomous system) numbers from IRR databases. Double click on a hop in a completed trace and NetScanTools Pro will query an IRR server for the AS number.
• Shows the Country that is allocated or assigned each IP address appearing in each hop.
• High resolution timing (sub-millisecond) for all modes except MS ICMP ping.
• Traceroute Graphing (hop vs time)
• MultiTrace - up to 16 successive traces are shown on a graph with hop vs time as axes.

**TCP Traceroute sends TCP packets to a user specified port (web server port 80 is recommended). TCP Traceroute will often work through firewalls protecting the target where the other types of traceroute will not, this is not guaranteed and depends on the target system configuration. Note that our specialized traceroute modes require the use of WinPcap. We install WinPcap as part of the installation package. WinPcap is designed for wired ethernet cards, not modems and it may or may not work with wireless interfaces.
