ipconfig
The “ipconfig” command can be used to show your current TCP/IP information, including your address, DNS server
addresses, adapter type and so on.
Figure 97 Ipconfig Command
In the example above, ipconfig was entered in the command prompt. The reply shows the PC’s IP address, subnet
mask and the gateway to which it is connected. Other ipconfig commands will return more information. The
hardware or MAC address of the computer may be discovered using the command ipconfig /all command. The
command “ipconfig /?” lists all of the commands and their usages available for use.
arp
Displays and modifies the IP to physical address translation tables used by Address Resolution Protocol (ARP).
Once a remote computer has been pinged, this command can be used to see the IP address and MAC address of
the remote computer. It will also show any other devices on the network to which it may be connected.
Figure 98 arp Command
The command used in Figure 98 is “arp -a”. It shows the PC’s IP address (like the previous ipconfig command).
In this case the IP address is still 192.168.0.17. It also shows the IP address and associated MAC address of any
another device that has a connection to it.
The command “arp -?” lists the commands available for this function.
