Network-wide MAC address search

Recently we put in a number of UPS's with network cards. We set static IPs on them but some of them seem not to have stuck. Is there any way to scan a network for mac addresses without taking an extremely long time doing a full IP sweep?

One of the problems with doing a simple network sweep is that if we have an IP scheme like 123.n.123.n (where 123 stays the same and 'n' changes based, first for location, and later for device assigned IP) if we were to say start with 123.1.123.1 and go to 123.50.123.255 it would check progressively through the 3rd octet, which is static.

Any advice would be much appreciated!

I would advise you to download a free tool called netscanner from here:
http://www.softperfect.com/download/freeware/netscan.zip

Then put in your subnet address and hit scan. It will scan all the ip addresses in your network and display information such as the mac address.

This will help you in finding your devices.

I use it all the time and it is one of the most helpful tools in an IT engineers toolbox.
