That makes sense, sound like I'm redoing in PHP what the UNIQUE column

SELECT device, count(hostname)
FROM your_table
GROUP BY device
HAVING count(hostname)>1;
This would display all devices with at least 2 (or more) hostnames.
If you always have the same IP address,

For example, the fields: device, hostname, IP, comments
