Because NT servers can (and often do) have more than one TCP/IP interface, you can specify which interface you want to view statistics for by placing its address on the command line with the switches. If you don’t specify, ipconfig displays information for all interfaces.

The tracert Utility

H ave you ever wondered where the packets go when you send them over the Internet? The TCP/IP Trace Route (tracert) command-line utility will show you every router interface a TCP/IP packet passes through on its way to a destination.

To use tracert, at a Windows 95/98 or NT command prompt, type tracert, a space, and the DNS name or IP address of the host for which you want to find the route. The tracert utility responds with a list of all the DNS names and IP addresses of the routers that the packet is passing through on its way. Additionally, tracert indicates the time it takes for each attempt. Figure 4.12 shows sample tracert output from a workstation connected to an ISP (Corporate Communications, in Fargo, North Dakota, in this case) in the search engine Yahoo!.
