I have a big class B network, I'm getting broadcasts from a device I don'k know, I need to find it's IP address, how can I do it? I only know it's MAC address.
Thanks.

Depends on what switches you are using to create that big network. On a cisco switch, you can issue: show arp, and it will show you all the IP->MAC it has in it's arp table.

If this is just one big network, just put a sniffer on there and filter in on the ethernet address.

Thanks for your answer. The switch are 3com 4200 series, I found an option to search the MAC address table, and even I couldnt find the IP, I could find where was the device fisically attached :) 
Thanks
