I have a managable switch and two managable hubs that i have to access to reconfigure their IP settings. The problem is that i don't know what hard coded IP address they are currently using so i am unable to access their management utilities via the web interface. They are not using the same IP address as the rest of the network. Their Mac address is written on the back of the hubs however.
My question: How can i reverse lookup their IP addresses using their know Mac address if i am on a different subnet that they are on?
