If you have an IP address conflict on your network system and you want to find out what hardware is taking that IP address you can use the command “nslookup”.

nslookup is a useful command used in Windows and in Unix.

If running in Windows, use the search bar and type in “cmd” then right click on it and choose “Run as administrator” then when at the command prompt enter:

nslookup

e.g.

nslookup 192.168.1.1

This will then tell you what hardware item already has that IP address. You can then change the ip address on that item to another IP address or just take that item off of the network by turning off wifi on it etc.
