Network-wide MAC address search
Posted on 2013-12-09
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 220.127.116.11 and go to 18.104.22.168 it would check progressively through the 3rd octet, which is static.
Any advice would be much appreciated!
