– ping.» Can be used to check for TCP/IP stack
initialization.» Checks for basic connectivity.» Uses ICMP echo requests.» Basic command format:
• You can ping XXX.XXX.XXX.XXX (the dotted decimal IP address).
• You can also ping www.google.com (the human friendly address).
» The behavior of ping can be modified; once in ping, type “/?” to find modifiers.

– tracert.» Microsoft implementation (traceroute = Unix,
Linux, and OS X).» Traces the route between two nodes.» Uses ICMP requests.» Logs responses from routers.» The utility has limited usability, as many routers
block ICMP requests.» Basic command format:
• You can tracert XXX.XXX.XXX to find the route to a destination.
• You can also use a human friendly address (e.g., www.google.com) with tracert to find the route.
» The behavior of tracert can be modified; once in tracert, type “/?” to get a list of available modifiers.

– netstat.» Used to list all inbound and outbound TCP/IP
connections on a given node.» Useful in determining which connections are
consuming network resources.
– net.» Most common use is to map a remote shared drive or
resource to the current node.• Example: C:\net use Z //bob.jones/shared.doc.
» Has other great uses: Do a Google search for “Windows 7 password recovery” to find them.
– nslookup.» Used to query DNS (Domain Name System) to
determine if a record exists.» Troubleshoots DNS issues.

nbtstat.Used to troubleshoot NetBios over TCP/IP.
Similar to arp, only with NetBios (NetBios is the human friendly name given to nodes in a Microsoft networking environment).
ipconfig.Used to list the IP configuration on a node.
A powerful tool, especially when used with ping and tracert.
arp.
Address resolution protocol utility.
Used to resolve IP addresses to MAC addresses. Use arp as a command to resolve arp table issus.

Summary
There are a number of command line utilities that can be used to assist with networking, including ping, tracert, netstat, net, nslookup, nbtstat, ipconfig, and arp. All commands can be modified by a “/” followed by the desired modifier (e.g., C:\>ping /a).
