Finding the IP address assigned to a computer is very simple. All you have to do is open the command prompt and use the IPCONFIG command. If you want to find the IP address associated with a specific computer name, you can use the NBTSTAT command. The syntax for doing so is as follows:
NBTSTAT -a <computername>
What if you want to find the computer name associated with a specific IP address? The solution is simple. You can once again find the information you are looking for using the NBTSTAT command, only this time with a different switch. Instead of using -a, you will use -A and specify an IP address as shown below:
NBTSTAT -A <ipaddress>
The results will tell you the computer name that is currently associated with the IP address you have specified.
