Determining the computer name associated with an IP address (Windows 2000 / XP / 2003 / Vista)
Adapted from a discussion paper by Diana Huggins in February 2005
Finding the IP address assigned to a particular computer on the network is quite simple. There is a DOS command that can be used and this has two distinct switches (-a and -A).
To discover 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>
The reverse of this is to find out the computer name associated with a specific IP address? Once again using the NBTSTAT command with a different switch 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.
The full explanation for the NBTSTAT command is as follows:
